Abstract
Electron spectroscopy has been carried out to investigate spectator and participant resonance Auger decay processes following the B 1s→2a2‘ excitation in gaseous BF3 molecules using monochromatized synchrotron radiation. The resonance‐enhanced satellite bands corresponding to the spectator Auger electron emission form six broad peaks showing good correspondence with the normal Auger bands. Resonance enhancement of the photolines corresponding to the participant Auger electron emission occurs only for the bonding orbitals having B character.
