Abstract
A new meclianism of spin-lattice relaxation (SLR) due to modulation of the dipole-dipole nuclear spin interaction by the rotation of the molecular preferential direction under diffusion along the pitch axis is suggested. The time of longitudinal relaxation (T1) is calculated for the pair of protons in the rapid diffusion limit. The estimate shows that this mechanism of SLR should be important in the low frequency experiments (10kHz-1MHz).Keywords
