✦ Synopsis
The vapor phase absorption spectra of PF 3, PFzCI, PFC12, and PC13 are reported in the vacuum ultraviolet spectral regicn 2400-1200 A. These results are compared with information obtained from photoelectron spectra. A brief discussion of the spectra in terms of analogous absorption regions and results from CND0/2 calculations are given. Only limited studies have been made of the vacuum ultraviolet (VUV) absorption spectra of phosphorus (III) halides. Humphries et al. [ 1 J earlier reported the spectra of PCI, from 2000-1300 8, and PF, from ISOO-1050 A. Absorprion bands containing vibrational structure in the two compounds were discussed in regard to the geometries of the excited states. Halmann [2] reported the spectra of PCI, from 2500-1860 a and later Holden [3] considered the spectra of PF, and PCI, in the region 2400-1200 8. In an effort to un-
