Photodissociative charge transfer in Ag+–pyridine complex

Ag+–pyridine complex has been generated in the gas phase. Dissociative metal-to-ligand charge transfer was observed through the photodissociation technique. Two continuum absorption/dissociation bands were recorded by monitoring the pyridine cation fragments as a function of the laser wavelengths and the possible dissociative mechanisms are discussed. The binding energy of the Ag+–pyridine was determined to be 45 kcal/mol. Ag+ bonding to nitrogen atom in C5H5N with ion–dipole interactions is suggested.
