Photodissociative charge transfer in Ag+-pyridine complex

Ag+-pyridine complex has been generated in the gas phase. Dissociative meta l-to-ligand charge transfer was observed through the photodissociation tech nique. Two continuum absorption/dissociation bands were recorded by monitor ing the pyridine cation fragments as a function of the laser wavelengths an d 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. (C) 1999 Elsevier Science B.V.
