✦ Synopsis

Spin-lattice relaxation times of 13C nuclei in pyridine and tetrahydrofurane

have been measured at various temperatures. Mainly dipole-dipole interaction was found to influence the relaxation behaviour below 273°K. Spinrotation, which predominates at higher temperatures, was found to contribute about 25% to the measured relaxation rates at room temperature. The components of the spin-rotation coupling constant, ~11 and cl have been determined for pure pyridine, using :esults from 'H and 14N relaxation. Anisotropic rotational diffusion was found for both organic molecules in their mixtures with water.
