High-resolution S 2p(-1) photoelectron spectra and S 2p(-1)-> X (1)A(1)(2b(1)(-2)) normal Auger electron spectra (AES) of H2S were measured for various photon energies in the range from 180 to 240 eV. The equilibrium geometry, vibrational energies h omega, and anharmonicities xh omega, for the S 2p(-1) intermediate and X (1)A(1)(2b(1)(-2)) final states were derived from the energy splittings and the intensity distributions of the vibrational substates. The relative intensities of the various S 2p(-1)-> X (1)A(1)(2b(1)(-2)) normal Auger transitions as well as the lifetimes of the various S 2p(-1) core-ionized states were also derived. In addition to the S 2p(-1)-> X (1)A(1)(2b(1)(-2)) transitions, some weak structures were observed in the AES, with intensities that exhibit pronounced photon-energy dependences.
