β¦ Synopsis
The He I induced valence electron spectrum of SiF4 is presented and the energies of the bands are reported. The spectrum reveals vibrational structure in three of the four accessible electron bands. Only the band at 19.5 eV has been reported previously to exhibit vibrational progressions.

A high-resolution study of the Si2p photoabsorption spectrum of gas-phase SiF, is reported. In the excitation region of the Rydberg orbitals, vibrational substates from symmetric stretching vibrational modes were resolved, which were described on the basis of a Franck-Condon analysis resulting in vi
