[Heat transitions in DNA molecule. The life-time of excited h-b-1 hydrogen bond in paired guanine-cytosine bases].
A theory of radiationless transitions of protons of the hydrogen bonds between the paired DNA bases is constructed. The lifetime of excited h-b-1 bond in guanine-cytosine pair is found to be 4.6 x 10(-9) sec. The dependence of frequencies, amplitudes and normal coordinates of heavy atoms (N, O) on the state of H-bond (ground or excited) are taken into account.
