Applications of 95Mo NMR spectroscopy. XIII. Relaxation times of molybdenum compounds

Abstract

The 95Mo spin-lattice and spin-spin relaxation times have been measured for a number of compounds with linewidths ranging from less than 1 to 1720 Hz. Corresponding relaxation times range from 7 s to 180 μs. The results indicate that quadrupole relaxation is the only significant mechanism involved, allowing the T1 values to be interpreted in terms of the electric field gradient, molecular size and shape, solution viscosity, temperature, and solvent-solute interactions. 97Mo relaxation times are also reported for the more highly symmetric compounds. © 1985.
