Abstract:

Rate constants for the quenching of biacetyl phosphorescence by alkenes at room temperature in benzene have been measured. Quenching constants correlate with the ionization potentials of the alkenes. Rate data from phosphorescence quenching for a number of ketones are compared and trends associated with formation and decay of electron donor-acceptor complexes of excited ketone triplets and alkene quenchers.
