Abstract

He I photoelectron spectra of gas-phase complexes formed by $Br_2$ with diethyl ether and diethyl sulphide have been studied and interpreted using ab initio MO calculations. The key spectral features are assigned to the highest occupied molecular orbitals derived from $Br_2$ and the donor molecule whose ionization potentials are shifted to lower and higher binding energies, respec- tively. All-electron and effective core potential calculations yield a $C_{2v}$ structure for $Et_2O$...$Br_2$ and a $C_s$ form for $Et_2S$...$Br_2$. The nature and magnitude of the interactions are found to be comparable as reflected by the computed binding energy and quantum of charge transfer.
