Hariharan and J. A Dictionary of Chemistry , Subjects: The well-known discrepancy between the number of the Bohr magneton obtained from the saturation magnetization at 0K and that obtained from paramagnetic susceptibilities for Ni is explained by taking into account the s d exchange interaction, instead of the s d electron transfer, and the temperature-independent paramagnetism due to the orbital moments of d electrons.

The SO-RASPT2 results fit well the experimental magnetic susceptibility and pNMR chemical shifts. The fitting of the temperature dependence of the pNMR chemical shifts and SQUID magnetic susceptibility by a two-Kramers-doublet model for the N p V I complex and a non-Kramers-doublet model for the P u V I complex allows for the experimental evaluation of energy gaps and magnetic moments of the paramagnetic center.
