Ne matrix spectra of the sym-C 6Br 3F 3+ radical cation

Abstract

The electronic absorption and laser excited, wavelength resolved fluorescence spectra of the title cation have been observed in solid Ne matrix and vibrationally analysed. The vibrational structure of the excited B 2A 2 ″ state shows close similarity to the parent compound. The X 2E″ ground state structure is strongly perturbed and irregular owing to a large Jahn—Teller distortion. The data are analysed in terms of a recently developed, sophisticated multimode Jahn—Teller theoretical model. We have generated the sym-C 6Br 3F 3 + cations in solid Ne matrix and obtained their wavelength resolved emission and absorption spectra. T ground electronic X 2E″ state exhibits an irregular and strongly perturbed vibrational structure, which can be successfully modeled using sophisticated multimode Jahn—Teller theory.
