Notes

1Approximate constants for the deperturbed state. Perturbed values are B0 = 5.79, ν0(0-0) = 43105.5. Rotational levels in v=0 are broadened: broadening increases with J. See 8.
2Q branches only having J ≥ 18.
3Ω-type doubling Δνef(v=0) ~ +0.006J(J+1) +0.00007 J2(J+1)2 - ...for J < 17. b 1 (v=0) perturbed by B 0+ (v=3) at J~18. Bands with v' ≥ 1 consist of Q branches only.
4Ω-type doubling Δνef(v=0) ~ -0.005J(J+1) + 0.00002 J2(J+1)2. Bands ascribed by Ringstrom, 1963 to v=4 and 5 (B4 = 4.60, B5 = 3.63) consist of Q branches only: line width increasing with J, see 8 .
5A and B correspond to 1Σ* and 1Σ**, respectively, of Heimer, 1936.
6Vibrational levels observed up to v=4. Levels with v ≥ 2 are strongly perturbed by C 1Σ+. For details see Ringstrom, 1963.
7Broadening, increasing with J, of rotational levels in v=3 and 4. See 8 .
8Predissociations in B 0+, a 2, and C 1Σ+ are due to interaction with an unstable 1 state arising from Au(2D5/2) + H(2S): see Ringstrom, 1963.
9D1 = 3.4E-4.
10Based on the value for the common dissociation limit Au(2D3/2) + H(2S) of states B, a, b,and c Ringstrom, 1963. Agrees within error limits with an earlier thermochemical value by Farkas, 1929.
11D1 = 7.6E-4.
12From the value for AuH.
13Approximate constants for the deperturbed state. Perturbed values are B0 = 2.954, ν0(0-0) = 43011.0. Constants for an additional level at 45122.8 cm-1 above X 1Σ+(v=0), assumed to be unperturbed and tentatively assigned as v=2, are B2 = 2.75, D2 = 8.3E-4.
14Average of the two Ω-type doubling components; Δνef ~ +0.0055 J(J+1).
15Vibrational levels observed for v ≤ 7, except v=6. Levels with v > 2 are strongly perturbed by C 1Σ+ Ringstrom, 1963. βe ~ +0.06E-4.
16Line width in 5 ← 0 band increases with J.
