Angle-resolved photoelectron spectroscopy has been carried out on the valence shell of SiCl/sub 4/ over the range of photon energies from 101.5 to 112.5 eV. Both intensities and angular distribution parameters ..beta.. were monitored over the preionization resonances for silicon 2p. Little effect was seen for emission from the chlorine lone-pair orbitals 2t/sub 1/ , 8t/sub 2/ , and 2e, but striking effects were seen for the bonding 7t/sub 2/ orbital. The resonant behavior was compared with photoabsorption data. The results are discussed in terms of direct participation of the resonantly excited electron and this process compared with spectator electron and shakeup processes.
