Abstract
The L23-VV Auger spectra for phosphorous atoms in the PH3, PF3 and PCl3 molecules have been recorded following 2p core-hole ionization induced by photons with energy in the range 150-170 eV. The chlorine L23-VV spectrum for the PCl3 molecule has also been recorded. The spectra have been interpreted with the aid of molecular Auger calculations. Differences due to chemical effects are identified and a valuable insight is gained into the major pathways available for Auger decay resulting in complex spectral profiles. Predictions are made for the phosphorous 2p inherent photoelectron linewidth in these molecules.
