Abstract

To begin with the present paper deals with compounds called photosensitizers, namely, psoralens (Ps), 21,22-dimethyl-10,11-cyclohexylpsoralen (DCP) and 10,11-phenyl-21,22-cyclohexylpsoralen (PhChP). The absorption spectra from excited triplets states, photophysical and spectral properties occurring in molecules were investigated in this paper. The triplet-triplet absorption spectra, spectrum S_o-S_i-absorption and rate constants of Ps, DCP and PhChP have been determined using INDO method. Experimental absorption spectra of PhCIiP were obtained using CM-2203 spectrofluorimeter.
