Abstract

Laser-induced fluorescence spectra of C₆F₆⁺ have been recorded in the gas phase. Excitation spectra of quality far superior to previous observations have been obtained by cooling the ions to near liquid N2 temperature. The improved S/N and resolution permit considerably more information to be obtained about both the ground X ²E_1g and excited B ²A_2u electronic states. Laser-excited, wavelength-resolved emission spectra have also been observed for C₆F₆⁺. These spectra allow direct observation of the Jahn-Teller perturbed vibronic structure of the ground state. Because of their relative simplicity, assignment and interpretation are usually unambiguous. Overall, the experimental results determine rather extensively and redundantly the vibronic structure of both electronic states.
