Abstract: Amethod for determinating the spin-internal rotation relaxation rate of methyl by ortho-subslituting and meta-substituting the sample ( toluene ) is suggested. Spin-lattice relaxation times ( T1 ) and nuclear Overhauser effect ( NOE ) of 13Cin the methyl of ο-xylene and m-xylene between 28℃ and 90℃ are measured. The spin-whole rotation relaxation rate and spin-internal rotation relaxation rate of 15Cin the methyl of m-xylene are separated, with the internal rotation rate of the methyl calculated.
