Extract

During the last twenty-five years the development of quantum mechanical calculations and experimental measurements of chemical shifts of the different type of nuclei present in nucleic acids have run parallel in close relation to each other. The first calculations dealt with intramolecular effects on base proton shifts (Veillard, 1962) but the real breakthrough of the theory occurred with the advent of computations of intermolecular shielding due to the ring current effect of the nucleic acid bases (Giessner-Prettre & Pullman, 1970).
