Abstract
The electronic absorption spectra of tetrahalide complexes of ZnII, CdII, HgII, and TlIII have been measured either in solution or as thin films. The effects of second-order spin–orbit coupling account satisfactorily for the observed band intensities and splittings. The one-electron transitions responsible for the lowest-energy groups of absorption bands are all of the type t2→a1. There is no evidence for transitions from the non-bonding t1 or e molecular orbitals, and an explanation is advanced for their non-appearance.Keywords
