The paramagnetic spin-lattice relaxation times of an isolated Ir4+ ion inserted in the crystalline lattice (NH4)2PtCl6 are computed. The computation is carried out for a Van Vleck relaxation mechanism taking account of the ...
The Van Vleck method is used with the point-charge model to calculate the spin-lattice relaxation times of the Ce3+ ion in binary nitrates. Normal coordinates are found for the icosahedral XY12 complex containing the ...
