摘要: the structural coordinates were obtained from a neutron diffraction study, no geometry optimization was needed in performing calculations. It is demonstrated that C–H···O hydrogen bonding has different influences on O2 and O4 EFG CS tensors. In tetramer model of 1-methyluracil, which much closer to real crystalline phase, influence tensors significant, whereas this negligible for O2.
