Abstract

The ultraviolet photoelectron spectrum of the $H_2S$ dimer shows four features with vertical ionization energies of 9.75, 10.95, 12.37 and 13.69 eV; the adiabatic ionization energies of the first two ionic states are 9.56 and 10.75 eV. Molecular-orbital calculations reveal that the first two features are due to the sulphur lone pairs while the others are due to the $\pi_{SH_2}$ orbitals. The ground ionic state $(1^2A")$ of the dimer is bound by 0.96 eV and the structure undergoes significant distortion on ionization. The first excited ionic state $(1_2A')$ is repulsive.
