The absorption spectrum from 450000 to 870000 cm-1 (55.8 to 107.9 eV) at low resolution has been described by Myer and Samson, 1970. It corresponds to excitation from 4d shell to various unfilled orbitals.
Comes, Nielsen, et al., 1973
The absorption spectrum in the VUV region at high resolution has most recently been photographed by Venkateswarlu, 1970 who gives an extensive table of observed features in the region 56500 - 75800 cm-1. Most of the bands are assigned to extended Rydberg series converging to a common limit at 75814 cm-1 (9.400 eV), a smaller number to fragments of series converging to 80895 cm-1 (10.03 eV). The limits are assumed to correspond to v=0 of X 2 Πg, 3/2 and 1/2, respectively, of I2+; see, however, 1. Several of the progressions observed in absorption Venkateswarlu, 1970 appear to correspond to emission bands recorded by Haranath and Rao, 1958 under medium resolution in the region 56000 - 68000 cm-1 and classified by them as belonging to twelve systems.

Notes

1From the photoelectron spectrum Potts and Price, 1971, Higginson, Lloyd, et al., 1973; adiabatic potential established by temperature variation. The same method yields 9.953 eV for the ionization potential to 2Π1/2g(v=0). Neither result agrees with the values obtained by Venkateswarlu, 1970 from Rydberg series, i.e. 9.400 and 10.03 eV. The discrepancy could be understood if the Rydberg series were to correspond to v'=3, but the absence of series with v' = 0, 1, 2 would still be puzzling.
2Weak emission bands in the presence of foreign gases, 2785-2731 . Te is based on the assumption that the lower state is the B state, but Mulliken, 1971, has suggested that instead it may be the D state leading to Te ~ 76872 cm-1 Mulliken, 1971.
3Strong emission bands in the presence of foreign gases, 3460 - 3015 Angstroms. It is by no means certain that the lower state has been correctly identified as the B state. Mulliken, 1971, suggests that the bands arise from the transition G → A'.
4From the intensity distribution and Franck-Condon principle Mulliken, 1971, Wieland, Tellinghuisen, et al., 1972.
5In emission in electric discharges in the presence of foreign gases, 2740 - 2490 . Also observed for 129 I2, confirming the vibrational numbering. Emission bands in the region 2240 - 1950 Angstroms are assigned by Haranath and Rao, 1958, to a separate system (called H → X), with v00 = 48072 and w ~ 79. It seems, however, possible that these bands belong to F → X.

7The analysis of this fairly extensive system [2400 - 2240 , called E → X by Haranath and Rao, 1958] is not yet supported by isotope studies, nor is it seen in absorption.
8Suggested upper state of high temperature absorption "continuum" shortward of 3263 (30640 cm-1)
9Configuration...σgπu4πg3σu2.
10Emission bands in the presence of foreign gases, 4400 - 4000 . Also observed for 129I2, confirming the vibrational numbering. The E → B fluorescence spectrum following two-photon absorption Rousseau and Williams, 1974, consists of transitions both to the discrete and to the continuous part of B, the latter giving rise to diffuse bands ("structured" continuum) Tellinghuisen, 1975. From a comparison of the calculated with the observed intensity distribution Tellinghuisen, 1975, obtains the potential function of E as well as the variation of the transition moment with r. The lifetime of E → B is 27 ns Rousseau, 1975 confirming that this is an allowed transition and that the E state is 3Π0+g.
11The v' numbering is uncertain and, therefore, the vibrational constants are subject to change.
12The system includes the absorption bands of Pringsheim and Rosen, 1928, Kimura and Miyanishi, 1929, Cordes, 1935, remeasured by Nobs and Wieland, 1966. It also includes the resonance series of Verma, 1960 in the region 1830 - 2370 which arise from very high vibrational levels (v' ~ 195), of the D state excited by the 1830 atomic line of iodine. The system further includes the diffuse emission bands in the region 2500 - 5000 with a characteristic group near 3250 [McLennan bands McLennan, 1913]. The diffuse bands have been recognized by Mulliken, 1971, to correspond to transitions from D to the continuum of X [Condon diffraction bands, see also Tellinghuisen, 1974]. Earlier summaries Mathieson and Rees, 1956, Haranath and Rao, 1958, Venkateswarlu, 1970 gave an electronic state at Te = 51427.9 with ωe = 169.41, ωexe = 0.941, ωeye = +0.0022 which was to represent the Cordes absorption bands from 1950 to 1795 Cordes, 1935. Following Mulliken, 1971, Mulliken, 1971, we consider these bands as part of D ← X.

15The G →A' transition has been observed to lase strongly when mixtures of HI or CF3I or CH3I with argon (1000 - 4000 torr), are excited by a pulsed high current electron beam Hays, Hoffman, et al., 1976. See also H → B footnote 3.

23Collision induced predissociation of the B state missing citation; magnetic field induced predissociation Degenkolb, Steinfeld, et al., 1969, Capelle and Broida, 1972, Chapman and Bunker, 1972; spontaneous predissociation Tellinghuisen, 1972; hyperfine predissociation Broyer, Vigue, et al., 1976. The purely radiative lifetime Brewer and Tellinghuisen, 1972, Tellinghuisen, 1972, Broyer, Vigue, et al., 1976, increases smoothly from τ= 0.91 μs at v=7 to approximately τ= 10 μs at the highest observed levels. The measured lifetimes Brewer and Tellinghuisen, 1972, missing citation, Capelle and Broida, 1973, Keller, Broyer, et al., 1973, Paisner and Wallenstein, 1974, Broyer, Vigue, et al., 1975 are considerably reduced by spontaneous predissociation due to rotational and hyperfine mixing with B" 1Π1u, the latter leading to differences in lifetime between ortho and para levels Broyer, Vigue, et al., 1976. Only near v=12 and above v~50 are the actual lifetimes close to the purely radiative ones. The magnetic field-induced predissociation of B 3Π0+u was previously assumed to be caused by B' 3Π0-u, and a potential function for this latter state was derived from magnetic quenching data Chapman and Bunker, 1972, Child, 1973. The recent observation, however, of a quantum interference effect between magnetic and spontaneous predissociations Broyer, Vigue, et al., 1973, Vigue, Broyer, et al., 1974, Vigue, Broyer, et al., 1975 has established that the magnetic predissociation, too, is produced by the B" 1Π1u state.
24gJ varies from -0.059 at low v to -5.45 μN near the dissociation limit; from Hanle effect observations Broyer and Lehmann, 1972, Broyer, Lehmann, et al., 1975, Gouedard, Broyer, et al., 1976, Gouedard, Broyer, et al., 1976, 2. See also Wallenstein, Paisner, et al., 1974.

26For v ≤ 10 Barrow and Yee, 1973. Dv increases rapidly above v=20; for more details see Brown, Burns, et al., 1973, Wei and Tellinghuisen, 1974.
27The continuum joining onto the discrete bands is overlapped by the B"← X continuum. A resolution of these two continua and the A ←X continuum was given by Tellinghuisen, 1973,. See also Tellinghuisen, 1973, 2.
28The hyperfine structure of several lines has been observed by various high resolution laser techiques; electric quadrupole, magnetic octupole, and other magnetic hfs constants have been evaluated Hanes and Dahlstrom, 1969, Kroll, 1969, Hansch, Levenson, et al., 1971, Hanes, Lapierre, et al., 1971, Sorem, Levenson, et al., 1971, Levenson and Schawlow, 1972, Sorem, Hansch, et al., 1972, Youmans, Hackel, et al., 1973, Ruben, Kukolich, et al., 1973, Bunker and Hanes, 1974, missing citation; similar analyses for 129I2 and 127,129I2 Tesic and Pao, 1975.
29Extrapolated from data with v' ≥ 4. The vibrational numbering, changed Steinfeld, Zare, et al., 1965, by 1 from the previous table in MOLSPEC 1, has been confirmed by isotope studies Brown and James, 1965.
30 Tellinghuisen, 1973, suggests that the v'=4 numbering of Brown, 1931, may have to be raised substantially. Preliminary results of a rotational analysis Ashby, 1975, of nine bands in the A ←X, v"=5 progression and of three bands in the v"=4 progression indicate that w' ~ 57.5 Ashby, 1975, w'x' ~ 1.85 Ashby, 1975, B'(for the lowest analyzed level) = 0.02375 Ashby, 1975, α' ~ 0.0005 Ashby, 1975.
31The continuum joining onto the discrete bands has been studied by many investigators, most recently by Tellinghuisen, 1973, who derives an f value of f= 0.00062 Tellinghuisen, 1973; see also Brith, Rowe, et al., 1975.

33These constants Barrow and Yee, 1973, represent the levels v=0-5; Wei and Tellinghuisen, 1974, for v=0-6, give ωe = 214.582, ωexe = 0.6243, Be = 0.037363, αe = 0.0001145 using calculated Dv values. On the basis of the resonance series of Rank and Baldwin, 1951, Rank and Rao, 1964 and Verma, 1960, LeRoy, 1970 has given polynomial formulae for G(v), Bv, and Dv valid up to v = 82; ωe = 214.548, ωexe = 0.6163 , ...Be = 0.037395, αe = 0.0001244, ... ,De = 4.54E-9, βe = 0.017E-9;... The most accurate constants for v = 0 were derived Gerstenkorn, Luc, et al., 1977 from the analysis by means of Fourier transform spectroscopy of the B←X, 30-0 bands: B0 = 0.0373115, D0 = 4.55E-9, H0 = -0.76E-15. The vibrational levels of the ground state have been observed up to v = 84 [D → X resonance series Verma, 1960], i.e. to within 400 cm-1 of the dissociation limit. The levels v" = 98...115 originally reported by Verma, 1960, were found to be due to an NO impurity Verma and LeRoy, 1974. As a consequence the RKR potential function of Verma, 1960, must be corrected at high v. The RKR curves of Zare, 1964 and LeRoy, 1970 extend only to v = 82 and are unaffected by this correction. 35 see 33.
