| Abstract: | The comparison of the photochemical properties of three aromatic and five aliphatic amino acids and three dipeptides was carried out using 212.8 nm laser irradiation and high performance liquid chromatography. The photochemical sensitivity, photolysis quantum yield and quantum yield of peptide bond scission were determined. Two-photon absorption coefficients of solvent (liquid water) and cell windows material (fused silica) at lambda = 212.8 nm were established. |
