title: [Temperature dependence of the electronic absorption spectra of polynucleotides and their components].
abstract: The temperature dependence of UV-absorption spectra of solutions nucleic bases, nucleosides, nucleotides and metilated bases, uncapable of tautomerization has been studied. The nature of such dependence, its connection with hypochromic effect is discussed. It is shown that for some methods of investigating polynucleotides it is necessary to take into account the temperature changes spectra of monomers.
