✦ Synopsis
The spin-internal rotation coupling contribution to spin-lattice relaxation has been separated from other mechanisms by using selective Tr measurements for the ring and methyl protons of toluene,p and m-xylene in various sol-vents_ This particular interaction is found to be an important part of the spin-lattice relaxation of methyl protons at room temperature.
