Abstract
It has been shown that the quantum yield of the photochemical conversion of adenine and the corresponding nucleosides and nucleoside 5'-phosphates in liquid (pH 5.6 and 2.0) and frozen aqueous solutions do not exceed 10(-4). The quantum yield of the photoconversion of guanine-containing nucleosides and nucleoside 5'-phosphates in liquid aqueous solution (pH 5.6) after removal of oxygen by passing through nitrogen and in the frozen state do not exceed 0.3 x 10(-4). The quantum yield in oxygen-containing liquid aqueous solutions increase to 0.3 x 10(-3), i.e. to values commensurate with the quantum yield of pyrimidine photolysis.Keywords
