Laser excited charge transfer processes in oxygen organic molecules mixtures: O(P-3(j)) formation

Laser induced charge transfer (CT) processes have attracted attention for m any years. These reactions play an important role in chemistry as well as b iophysics and biology. When the reaction is induced by laser on a complex f ormed in a supersonic beam, the impact geometry is well defined and reactio n details are more evident. This paper deals with features relevant to O-2 photodissociation induced in clusters of oxygen molecules and rare gases, w ater or organic molecules. Our studies, performed in a supersonic beam by u sing lasers of different wavelength to induce the reaction and to detect th e reaction products by multiphoton ionization, show that production of atom ic oxygen is strongly dependent on the ionization potential of the electron donor.
