The phosphorescence from three model bicyclic enones and those formed in thermally oxidized poly{butadiene) has been shown to be quenched efficiently by a nitroxide [3,3,4.4-tetramethyldiaze-tine N,N'-dioxide] in CH2CI 2:tetrahydrOfuran glass at 77K.

Quenching of aromatic excited singlet states (9,10-dimethyl anthracene, 9,10-diphenyl anthracene and perylene) by nitroxyl radical was studied by flash photolysis and fluorimetrically. It is established that the dominant quenching mechanism is enhanced intersystem crossing in the collision complex w
