Localization of the energy of electronic vibrational excitation and selective laser chemistry

The paper describes a method for the selective photochemical transformation of polyatomic molecules of different classes in excited vibrational electron states (S-asterisk, T sub 0, and T-asterisk). The method is based on the effect of localization of the energy of vibrational electron states on separate fragments (oscillators) of molecules of appropriate classes and spectral-luminescent groups. The method can be used to realize selective (laser) photochemistry (e.g., of ketones and their derivatives), polymerization and polycondensation of certain compounds, the initiation of catalytic reactions, isotope separation, etc.
