TEMPERATURE-DEPENDENCE OF THE ELECTRON SPIN-LATTICE RELAXATION IN LITHIUM-METHYLAMINE SOLUTIONS
The temperature dependence of the electron spin-lattice relaxation time, T1e, is reported for the lithium-methylamine system. Samples of 6.5-21.1 mol % metal (mpm) have relaxation times in the range 0.6 × 10-7-8 × 10-7 s. The electronic g factor is 2.00172 ± 0.00002 for all concentrations. It is dem...

Summary: | The temperature dependence of the electron spin-lattice relaxation time, T1e, is reported for the lithium-methylamine system. Samples of 6.5-21.1 mol % metal (mpm) have relaxation times in the range 0.6 × 10-7-8 × 10-7 s. The electronic g factor is 2.00172 ± 0.00002 for all concentrations. It is demonstrated for this nonfluctuating system that dT1e/dT is a sensitive means for determining the concentration at which the metal-nonmetal transition occurs. The present study indicates this transition takes place between 13.4 and 15.6 mpm in the temperature range 160-260 K. © 1980 American Chemical Society. |
