Özet
Spin-lattice relaxation times in one of dibenzo diaza 18-crown-6 ether derivative were measured vs. increasing temperature. The relaxation times (In T-1) were fitted vs. I/T over a temperature range of 313-277 K. A linear relationship with a negative slope was found for each peak. The present data suggest that In T, is nearly linearly proportional to I/T. The data also suggest that dipole-dipole interaction, modulated by whole molecular tumbling, is the source of relaxation.
