Paper Abstract

A comparison of photochemical properties of three aromatic and five aliphatic amino acids as well as seven peptides in neutral liquid aqueous solution at five different wavelengths was carried out. The photolysis quantum yield and the quantum yield of peptide bond scission were determined for the first time. The experimental dependence of tryptophan photodecomposition efficiency versus the energy excess above the ionization threshold confirms recent theoretical predictions of photoionization properties of molecules in diluted aqueous solution below the bottom of the conduction band.
