The Electron-photon Emission of the Nitrogenous Basis of Nucleic Acids - a Cytosine in a Solid Phase

| Summary: | For the first time the method of an electron - photon spectroscopy (EPhS) has studied a luminescence of the molecules of the nitrogenous basis of nucleic acids adsorbed on the surface of graphite – a cytosine – under the influence of a bunch of electrons of low energies. The luminescence of three molecular strips with maxima at λ= 331, 427, 495 nm is revealed. The mechanism of formation of strips with maxima at λ= 331 nm and λ= 427 nm caused by excitement of π-electrons of a molecule of a cytosine from the main condition of S0 in the excited singlet Sn and triplet Tn state with their subsequent deactivation and radiation collapse. The radiation nature is discussed with a maximum at λ= 495 nm. |
