Essay

The work has been devoted to the complex study of excitation and ionization processes of nitrogenous bases of nucleic acids, such as adenine and guanine molecules by electron impact. The adenine and guanine mass spectra are measured. The absolute values of ionization and partial ionization cross sections of adenine and guanine molecules are determined and propose the most probable schemes of fragmentation of these molecules under the action of the electron impact. The luminescence spectra of adenine and guanine molecules by electron impact with energy 20, 40, 60, 80, 100 eV using vapor-filled cell and luminescence spectra of vapors of these molecules in the wavelength range of 200–500 nm are measured and propose their identification.
