Abstract
Sensitization of Crystal Violet (CV), in benzene solutions, by triplet states of benzophenone, biphenyl and benzene itself has been observed . The resulting transient spectrum and its decay kinetics have been st udied in the 360-450 nm region. The observed spectrum has been attribu ted to triplet state of CV. The rate constant for energy transfer from triplet benzene to CV has been estimated to be 5 x 10(10)dm(3) mol(-1 ) s(-1). Triplet state of CV is found to decay by reacting with the pa rent dye molecule with a rate constant 4 x 10(6) dm(3) mol(-1) s(-1). Copyright (C) 1997 Elsevier Science Ltd
