Several groups of diffuse emission bands in the region 23600 - 50000 cm-1 have been assigned Venkateswarlu, 1947 to transitions from four states at 47000, 55534, 61444, 66500 cm-1 to various repulsive states arising from Br(2P3/2,1/2) + Br(2P3/2,1/2) .

1The interval of 3141 cm-1 between X1 2Pi3/2 and X2 2Pi1/2 of Br2+ derived from the Rydberg series does not agree with the value 2820 cm-1 from the photoelectron spectrum Cornford, Frost, et al., 1971. The discrepancy may be accounted for by assuming that instead of v'=0 as suggested in Venkateswarlu, 1969 the 2Pi1/2 series listed here have v'=2 while the 2Pi3/2 series have v'=1 (see 2).
2According to the photoionization and photoelectron value of the ionization potential (see 26) the five 2Pi3/2 Rydberg series in the table refer to v'=l. Vibrational structure; see Venkateswarlu, 1969.
3Normal isotopic mixture.
4Extensive system of absorption bands in the region 59000 - 67000 cm-1; no analysis. This system may include transitions to the upper states of:
5a) emission systems of Haranath and Rao, 1958
6b) a long resonance series (63817 - 53779 cm-1).
7The vibrational analysis is doubtful since only v"=21-32 were observed. v00 (extrapolated) and Te are different from Verma, 1958 to allow for the new data on the B state Barrow, Clark, et al., 1974.
8System H-X of Haranath and Rao, 1958, not observed in absorption.
9omegaeze= +0.000065; vibrational constants from the reanalysis Wieland, Tellinghuisen, et al., 1972 of the emission data of Venkateswarlu and Verma, 1958 and the absorption data of Briggs and Norrish, 1963. See 10 .
10It is not entirely certain that the lower state is B 3Piu,0+ and not A 3Piu,1.
11Several absorption continua beyond 19580 cm-1 corresponding to a number of electronic transitions including that to C 1Piu with maximum at 24000 cm-1.
12Also observed in magnetic circular dichroism Brith, Rowe, et al., 1975 and photofragment Oldman, Sander, et al., 1975 spectra. The latter authors confirm Mulliken's Mulliken, 1940 prediction that C 1Piu dissociates into 2Pi3/2 + 2Pi3/2 and observe evidence for several excited g states by two-photon photofragment studies near 28000 and 38000 cm-1.
13(for vleq8). Vibrational levels observed to v=55, dissociation limit (2P3/2+2P1/2) at 19579.76 cm-1 above X 1Sigmag+(v=0,J=0). See 16. Absorption in the B 0u+ continuum Bondybey, Bearder, et al., 1976.
14Hfs observed in v=12 (81Br2) and v=17(79Br2); see Eng and LaTourrette, 1974.
15Predissociation was observed Lum and McAfee, 1975, Lum and Hozack, 1975 for v=42, J=33 by the laser-molecular beam technique. B rarrow X emitted in the recombination of Br(2P3/2) atoms shows strong enhancement of bands with 5<v'< 10 presumably on account of inverse predissociation Clyne, Coxon, et al., 1971. See also 18.
16RKR potential function and Franck-Condon factors Coxon, 1971, Barrow, Clark, et al., 1974. For the behavior of the potential function near the dissociation limit 13 see Goscinski, 1972, Yee and Stone, 1973, LeRoy, 1974.
17Dv and higher order constants in Barrow, Clark, et al., 1974.
18Estimated radiative lifetimes for A and B range from 1000 to 2000 and 12 to 70 mus, respectively Coxon, 1972, Coxon, 1973, Bondybey, Bearder, et al., 1976. For the B state Capelle, Sakurai, et al., 1971 find total lifetimes of the order of 1 mus; minima (~0.2 mus) occur for v=1 and 14 probably on account of predissociation. For lifetimes near the dissociation limit 13 of B see McAfee and Hozack, 1976.
19Convergence limit for 79Br2 at 15894.6 cm-1 above X 1Sigmag+ (v=0,J=0), corresponding to 2P3/2 + 2P3/2. A weak continuous spectrum joins onto the limit and overlaps the main absorption system B larrow X; see Sulzmann, Bien, et al., 1967.
20Extrapolated from v=7; constants for v=0.. .6 have not been determined. Bv, Dv, Hv, and Lambda-type doubling constants for v=7...24 in Coxon, 1972.
21RKR potential function and Franck-Condon factors Coxon, 1972.
22Based on DeltaG'(v=0-7) from low-resolution emission spectra Clyne and Coxon, 1967 of normal Br2 and the origin of the 7-0 79Br2 band at 14739.14 cm-1 derived from Coxon, 1972 and Barrow, Clark, et al., 1974.
23RKR potential curve Coxon, 1971, Barrow, Clark, et al., 1974. Hfs observed Eng and LaTourrette, 1974 in v=4 (81Br2) and v=7 (79Br2).
24Raman sp. 29
25From Barrow, Clark, et al., 1974; corresponding values for 79,81Br2 and 81Br2 are 1.97082 and 1.97095 eV (short extrapolation of B 0u+)
26From photoionization Dibeler, Walker, et al., 1970; supported by measurements at different temperatures. In good agreement with 10.51 eV obtained by photoelectron spectroscopy Frost, McDowell, et al., 1967, Cornford, Frost, et al., 1971, Potts and Price, 1971. A slightly higher value, 10.56 eV, was derived Venkateswarlu, 1969 from the Rydberg series in the VUV. It is probable that this value refers to v'=1.
27System J-X of Haranath and Rao, 1958, not observed in absorption.
28(valid for vleq8).
29Resonance Raman spectra in the gas Holzer, Murphy, et al., 1970, 2, Baierl and Kiefer, 1975, in solid argon Ault, Howard, et al., 1975; pure rotational Raman spectrum Baierl, Hochenbleicher, et al., 1975.
