Notes
1 | Λ-type doubling |Δv| = 0.1275J(J+l) - 0.54E-4J2(J+1)2. |
2 | Sequence of nearly undegraded bands; the origins of the 1-1 and 2-2 bands are at 61554.5 and 61560.7 cm-1, respectively. |
3 | A0 = -115.71, A1 = -115.20; see Rostas, Cossart, et al., 1974 who give also centrifugal distortion corrections AD as well as estimated spin-spin and second-order spin-orbit parameters. |
4 | Estimated using isotope relations. |
5 | For Λ-doubling constants see Rostas, Cossart, et al., 1974. |
6 | B1 = 7.5492. No emission has been observed from v=1 of PH, probably owing to weak predissociation by the repulsive 5Σ- state arising from ground state atoms Rostas, Cossart, et al., 1974. |
7 | D1 = 6.54E-4, H0 = -1.6E-8. |
8 | Lifetime τ= 0.45 μs, corresponding to an absorption oscillator strength of 0.0078 Fink and Welge, 1964. |
9 | Subband origins as defined by Rostas, Cossart, et al., 1974. |
10 | Theoretical predictions Jordan, 1964, Cade, 1968, Liu, Legentil, et al., 1972, for a 1Δ confirmed by laser photoelectron spectrometry of PH-[see ref. Ishaque and Pearse, 1939 of PH-). |
11 | Rotation sp. 15 |
12 | Constants deduced from isotope relations Rostas, Cossart, et al., 1974. |
13 | Spin splitting constants λ0 = +2.212, γ0 = -0.0738; λ1 = +2.207, γ1 = -0.0726 Rostas, Cossart, et al., 1974. |
14 | Adjusted theoretical value recommended by Meyer and Rosmus, 1975; see also Jordan, 1964, Cade and Huo, 1967, Liu, Legentil, et al., 1972. |
15 | N=4→5 rotational transitions observed by the laser magnetic resonance method. |
16 | From the value for PH. |
17 | A0= -115.74, A1= -115.55; see also 3. |
18 | B1= 4.0047. |
19 | D1= 1.640E-4. |
