Notes

1State causing perturbations and predissociations in B 3Σ-.
2The constants given represent the best approximation for v ≤ 6 Norrish and Oldershaw, 1959.
3Vibrational levels observed to v'=30, very close to the convergence limit S(1D)+O(3P) at 52500 ± 100 cm-1 McGrath and McGarvey, 1962, Colin, 1969. A large drop in the value of ΔG occurs near v=16 owing to an avoided crossing with another 3Σ- state Abadie and Herman, 1963, Colin, 1969. Lower vibrational levels appear to converge to a limit at ~ 59090 cm-1 corresponding to S(3P)+O(1D).
4Strong rotational perturbations, particularly for v=1 and 2 Martin, 1932, Abadie and Herman, 1964, Abadie, 1970 and v=7, 11 Colin, 1969. Predissociation (breaking-off in emission) for v=0, 1, 2, 3 above N=66, 53, 39, 6, respectively Martin, 1932, leading to a dissociation limit near 43224 cm-1. A second predissociation (diffuseness in absorption) sets in above v=8 and reaches its maximum for v=14, 15, substantially above the corresponding dissociation limit 3P + 3P Colin, 1969.
5Spin splitting constants λ0 = 3.5, γ0 = 0.010 or -0.020 Powell and Lide, 1964.
6Radiative lifetimes τ = 17.3 ns, τ= 16.6 ns, τ= 16.2 ns for v=0, 1, 2, respectively Smith, 1969.
7Franck-Condon factors Smith and Liszt, 1971, Hebert and Hodder, 1974; measured relative intensities, variation of electronic transition moment with r Hebert and Hodder, 1974.
8Constants derived from v=1...4; v=0 is perturbed. ΔG(1/2) = 425, 416, 414 for 3Π0, 3Π1, 3Π2, respectively. ΔG decreases rapidly above v=4.
9Radiative lifetime τ = 12.4 ns corresponding to a band oscillator strength f ~ 0.018 near the Franck-Condon maximum (2-0 band); see Smith, 1972.
10Approximate origins for the deperturbed 0-0 band, by extrapolation from the unperturbed levels v=1...4; see 8.
11Λ-type doubling Δ vfe = +0.00031J(J+1).
12Λ-type doubling Δ vfe ~ +1.2 cm-1, slightly dependent on J.
13Vibrational constants of Bouchoux, Marchand, et al., 1971; the older values of Norrish and Oldershaw, 1959, Colin, 1968 are based on an extrapolation of the ground state vibrational levels Martin, 1932 required by the revised v" numbering of Norrish and Oldershaw, 1959. This change has been confirmed by isotope studies Apparao and Narasimham, 1969. IR fundamental in Ar matrix: ΔG(1/2) = 1136.7 Hopkins and Brown, 1975.
14D1 = 1.30E-6.
15From a comparison with O2 and S2 Colin, 1968.
16"True" B0 of Clark and de Lucia, 1976; the effective value is 0.7103476.
17Microwave sp. 24
18The 33S hf interaction has been studied by Miller, 1971.
19Spin splitting constants λ0 = +5.2787981 cm-1, λ1 = +5.3105, γ0 = -0.0056153 cm-1, γ1 = -0.00572 Clark and de Lucia, 1976. For an improved representation of the rotational levels according to the intermediate case "c"- case "e" coupling model see Veseth, 1973, Veseth and Lofthus, 1974, Veseth, 1975; for an ab initio calculation of the spin-orbit part of 11 (dominant contribution to the observed splitting) see Wayne, 1975. Rotational constants for 34S16O, 32S18O, 33S16O are given in Tiemann, 1974, Tiemann, 1974, 2.
20IR sp. 25
21μel = 1.55 D from Stark effect of microwave spectra Powell and Lide, 1964. The hf interaction due to 33S has been studied by microwave Amano, Hirota, et al., 1967 and ESR spectroscopy Carrington, Levy, et al., 1967, 2; see also Veseth, 1976.
22From the first predissociation limit in B 3Σ- (see 4) assuming that it corresponds to dissociation into 3P2 + 3P2. A similar value (D00 = 5.364 eV) follows from the assumption that the convergence limit of the B state (see 3) corresponds to S(1D)+O(3P2). The value given here has been confirmed by thermochemical measurements Colin, Goldfinger, et al., 1964; see also Gaydon, 1968.
23From the photoelectron spectrum Jonathan, Smith, et al., 1971, Dyke, Golob, et al., 1974.
24μel = 1.32 D [average of values obtained from Stark effect of ESR missing citation, Byfleet, Carrington, et al., 1971 and microwave Saito, 1970 spectra].
