Abstract

Absorption spectra of the excited and ionic states of threo- and erythro-N-acetyl(1-pyrenylalanine)ethylester were measured by ps and ns laser photolysis methods. Interchromophoric interaction affecting the absorption spectrum was observed only in the excited singlet state, while neither triplet excimer nor dimer cation was detected. The present results are quite different from those of other bichromophoric systems, which were ascribed to rather distant structures of relevant chromophores in dipeptides.
