Vibrational and Vibronic Structure in the Valence Electron Spectrum of H2S

Abstract

The high resolution HeI induced electron spectrum of H₂S is presented and the energies of the observed vibrational and vibronic bands are reported. In the ² B ₁ electron band two progressions of vibrational bands have been measured. In the ² A ₁ electron band the vibronic structure associated with v ₂ bending vibrations has been partially resolved. Assignments of the vibronic bands are suggested from a comparison with electronic emission data in terms of the vibrational and angular momentum quantum numbers v ₂ and K.
