Notes

1A = -212 cm-1 [theoretical value Walker and Richards, 1970].
2From the photodetachment spectrum Zittel and Lineberger, 1976.
3Franck-Condon factor analysis of the photodetachment spectrum Zittel and Lineberger, 1976.
4From D00(PH) and the electron affinities of PH and H. Notice, however, that the ground 2Pi state of PH- cannot dissociate into P(4S) + H-(1S) but must correlate with the slightly higher limit P-(3P) + H(2S) at 3.31 eV. The atomic electron affinities are taken from Hotop and Lineberger, 1975.
