Shielding tensors paramagnetic contribution

A common origin paramagnetic contribution can subsequently be obtained as the difference between the LORG total shielding tensor and the diamagnetic contribution from eq.(29), i.e. [Pg.203]

The interaction between the orbital magnetic moment of the electrons and the nuclear moment can also be separated into an isotropic part (the chemical shift) and a traceless symmetric part (the shift anisotropy). The equation for the shift tensor contains two terms, usually called the dia- and paramagnetic contribution, but only the sum of the two corresponds to a physical quantity. Actually, the theory (76) is concerned with the shielding important difference between the two... [Pg.19]

Direct relationships between the P NMR parameters and structure are complicated by the fact that the chemical shifts are determined in phosphorus compounds predominantly by the paramagnetic rather than the diamagnetic contribution to the shielding tensor. This paramagnetic term is not necessarily directly related to the bonding electron... [Pg.438]
