Photogeneration of ions via delocalized charge transfer states. I. Xe2H+ and Xe2D+ in solid Xe

Abstract

Delocalized charge-transfer excitations in solid xenon multiply doped with atomic halogens (I, Br, Cl) and hydrogen are demonstrated to lead to charge separation by trapping of the positive charge. As evidence of such a concept we present the first vibrational spectra of Xe2H+ and Xe2D+, which are believed to be vibrationally bound ions.
