Abstract

Abstract: The CIDEP signal generated in the photochemical process in phenothiazine and 2,2,6,6-tetramethyl piperidingloxyl system can be interpreted by the radical-triplet piar mechanism(PTPM) prposed by Blätter. Furthermoce, the results obtained from fluorescence quenching and photoacoustic calorimetric measurements provide direct confirmation that the assumption of radical (TEMPO) only selective quenching the triplet in the doublet spin state of the radical-triplet pair.

Key words: TRESR, CIDEP, Radical-triplet pair mechanism
