The T$\sb1$ values agree well with those of previous investigators. The values of T$\sb1$ and T$\sb2$ were equal for each alkane studied. Empirical correlations were found between T$\sb1$ and two parameters: the acentric factor and the rotational coupling coefficient. The product $\eta$T$\sb1$ was constant for all the alkanes except n-pentane. The spin-lattice relaxation time was dedimensionalized and a three parameter corresponding states correlation was developed following the treatment of Tham and Gubbins (42) for transport coefficients. Excellent correspondence was found for the saturated alkanes over the temperature range 22 to 90$\sp\circ$C and for benzene from 12 to 63$\sp\circ$C. Spin-lattice relaxation times of mixtures of n-hexane and n-hexadecane were measured at 25$\sp\circ$C. The decay of magnetization could not be described by a single exponential curve. The results were analyzed using three methods.
