Abstract
Electronic excitation of H2S by impact with near-threshold-energy electrons has been studied. Comparison of the electron scattering data with optical spectra has led to the location of a number of optically forbidden electronic states. Of these, states at ca. 5.4 and 5.8 eV excitation energy are assigned as the lowest-lying triplet states 3B1 and 3A2′, respectively. A broad energy-loss band at ca. 7.4 eV is assigned to a valence-excited state of 1A2 symmetry, while structure at 8.55 eV is ascribed to excitation of a Rydberg 1A2 state.Keywords
