General analytical formulae describing the various contributions to the total spin-lattice relaxation rate in metallic materials (single crystals or powders) are presented. The formulae are obtained in the tight-binding approximation and can be easily used for any point-group symmetry. The cubic (O(
Proton spin-lattice (T1) and spin-spin (T2) relaxation times have been measured for CH3 protons in a series of paramagnetic transition-meta! acetylacetonatc complexes and the results interpreted in terms of current relaxation theory. r&the correlation time for molecular reorientation, was estimated
r3C spin-lattice relaxation times have been measured for some of the ligand positions of some metal acetylacetonate complexes. The results suggest that the relaxation process is dominated by dipolar interactions with unpaired eiectron spin residing on the ligand. A simple analysis of ligand-centred
