Abstract.
Photoinduced dissociation in the ultraviolet region has been investigated for Ag nF n-1 + cluster ions. Photodissociation spectrum of Ag2F+ in the energy of 3.8–5.6 eV exhibits several sharp bands corresponding to the transition to electronically excited states. In this dissociation, only the Ag2 + ion was observed as a fragment ion. Theoretical calculation indicates that the parent Ag2F+ ion has a linear Ag-F-Ag equilibrium geometries in the ground and excited states. Since conformational changes by excitation of bending vibration are necessary for the fragmentation of an F atom, this indicates that production of Ag2 + from Ag2F+ is a result of internal conversion and following conformational changes.
