Applications of super(95)Mo NMR spectroscopy. Relaxation times of molybdenum compounds

The super(95)Mo 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 mu s. The results indicate that quadrupole relaxation is the only significant mechanism i...

Zusammenfassung:The super(95)Mo 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 mu s. The results indicate that quadrupole relaxation is the only significant mechanism involved, allowing the T sub(1) values to be interpreted in terms of the electric field gradient, molecular size and shape, solution viscosity, temperature, and solvent-solute interactions. super(97)Mo relaxation times are also reported for the more highly symmetric compounds.
