Effect of glassy modes on electron spin-lattice relaxation in solid ethanol

▸ We study effect of glassy modes on spin-lattice relaxation of TEMPO in ethanol. ▸ EPR results indicate that effect is governed by electron-nuclear dipolar coupling. ▸ Relaxation mechanisms with glassy modes are calculated using soft-potential model. ▸ Calculated relaxation rates for glassy ethanol correlate with experimental data.
