| Abstract: | A method of calculating the hypochromism of polynucleotides in the nearest neighbour approximation is given by perturbation theory. The calculated hypochromism values of the first UV-absorption band of polynucleotides poly(dA)·poly(dT) and poly(dG)·poly(dC) are in good agreement with experiment. In this approximation the origin of the hypochromic effect is studied for the double-stranded polynucleotides; the dependence of the hypochromism upon the length of the polynucleotide is given. |
