| Abstract: | The contribution to magnetic shieldings of the anisotropy of the atomic susceptibility tensors is calculated and added to the ring current effect for nuclei located in a plane at z = 0.35 nm above the surface of the conjugated rings of the aromatic amino acids of proteins and of porphyrin. The variation of this contribution with the value of z is compared to the variation of the ring current effect. |
