The active centres in the initial stage of methacrylonitrile anionic polymerization have been studied by means of electronic and i.r.-spectra as well as by use of model compounds.

The spectral peculiarities of the DNA, the polynucleotide poly(dAdT) 2 , the oligonucleotide d(CCCGGGTTTAAA), the trimer d(ATC) and the low molecular model compounds dGMP, dAMP, dCMP and dTMP were studied. The system of energy sites and electronic processes in the DNA were examined. The lowest excit
