Abstract: | Frequency dependence of intermolecular proton spin-lattice relaxation rate [(1/T1)inter(ω)] in neat acetonitrile-d2 was studied. From (1/T1)inter(ω) pair-diffusion constants were determined to be 0.281 × 10?5 and 0.237 × 10?5 cm2 s?1 at 22 and ?32.6°C, respectively. These values differ greatly from the self-diffusion constants. |
