| dc.description | The results of calculations of nuclear magnetic resonance (NMR) parameters for the lead halides is reported in this paper. The results are obtained by using four-component methods. The use of the nonrelativistic Lévy-Leblond Hamiltonian along with the relativistic Dirac-Coulomb and spin-free ones allows us to discriminate scalar and spin-dependent effects on the parameters. It is found that the wide range of the lead NMR spectra and their large anisotropies are, mainly, due to spin-dependent effects on the paramagnetic term. Among the relativistic scalar corrections, the so-called spin-Zeeman kinetic-energy term turns out to be dominant. The reduced spin-spin coupling constants become proportional to the product of the atomic numbers of the coupled nuclei. | |
