摘要：
The metal nuclei spin-lattice relaxation rate and Knight shift data, obtained mainly by us, have been used to study the electronic density of states N(E(F)) at Fermi level and orbital magnetic susceptibility. Analysis includes all, except of HfH-2, transition metal dihydrides. The results have been compared with N(E(F)) obtained from the specific heat measurements and electron band calculations. It has been pointed out that, in contrast to cubic phases, the observed anisotropy of Knight shift (Ti-47, Ti-49 and Zr-91) in tetragonal TiH2 and ZrH2 indicates the orbital susceptibility anisotropy and/or electron spin dipolar contributions.
