Deposition of mass-selected ions in neon matrices: CS₂⁺ and C₆F₆⁺

Infrared and visible absorption spectra and laser-induced fluorescence (LIF) and excitation spectra are obtained for several simple cations deposited from a mass-selected ion beam. In the present preliminary study we demonstrate successful and clean mass selection by presenting spectra of samples ob...
