Abstract: Proton spin-lattice T1 and spin-spin T2 relaxation times of the n-alkanes from n-pentane to n-hexadecane were measured at 298.15 K. The T1 measurements essentially agreed with those of Kashaev et al. [1]. No spin-spin relaxation times of the pure alkanes were found in the literature to compare with our data. The temperature dependence of the relaxation rates of these alkanes follow the ratio of the viscosity divided by the temperature. The spin relaxation rate is dedimensionalized using corresponding-states parameters derived from a hindered-rotational model. The resulting three-parameter corresponding-states relationship is found to be closely obeyed by these alkanes.
