Abstract

Combined theoretical and experimental studies of rotationally resolved photoelectron spectra for single‐photon ionization of the outermost valence orbitals of H_2O, H_2S, H_2CO, and CH_3 are reported. Agreement between calculated and measured spectra is very encouraging. Both show that photoionization dynamics is very molecular in origin for H_2O, H_2S, and H_2CO but quite atomiclike for CH_3. Parity selection rules and the angular momentum composition of the photoelectron are used to illustrate the dynamical aspects of photoionization of polyatomics as molecular symmetry changes in a group of structurally related systems.
