Electronic and vibrational spectra of [Me4N]2UO2Br4

Abstract

Raman and polarized infrared, electronic absorption and luminescence spectra have been recorded for [Me₄N]₂UO₂Br₄ at temperatures down to 6 K. In contrast to a previous study the spectra are interpreted in an analogous manner to those of the corresponding tetrachloro complex. Eight electronic origins have been located in the low-energy region of the absorption spectrum. The static and vibronic intensity mechanisms are discussed under the model of Denning.
