Abstract
Electron spin-lattice relaxation rates for the low-spin [Rh(CN)(6)](4-) com plex in KCl were measured by the inversion recovery and saturation recovery techniques, in the range of 5 to 30 K. Angular variation experiments indic ate that electron spin-lattice relaxation times present axial symmetry. The data fit very well to a relaxation process involving localized anharmonic vibration modes, also responsible for the g tensor temperature dependence. (C) 2001 Academic Press.
