Description NMR parameters of the phosphorus atom in nucleic acids were subject of theoretical investigations in late 70s and 80s using semi-empirical or ab-initio CHF approach. The complexity of studied systems and results were limited by the computational power and theoretical background available at the time. We will describe a detailed of the conformational dependence of 31P chemical shift tensors in RNA and DNA using up-to-date methodology. For the first time, the orientation of the phosphorus chemical shift tensors in all canonical and several non-canonical of the RNa and DNA sugar-phosphate backbone is investigated in detail as a function of torsion angles and solvent interactions. Several models are inspected with respect to their size and the patterns of the hydration shell. The results are compared to experimental data.
