Chemical-evolution in glycilglycine (Gly2) films irradiated by 146 nm light was studied. It was found that quantum efficiency of chemical evolution from Gly2 to glycilglycilglycine (Gly3) is smaller than that to glycilglycilglycilglycine (Gly4) due to the multiple step of reaction. From natural circular dichroism spectra measurements for serine and alanine films, we found the splitting of 1s$$rightarrow$$$$pi$$$$^{*}$$ transitions in the energy region of oxygen 1s.
