Proton spin-lattice relaxation measurements were carried out by the rapid-passage method on the hydroxyl and methyl protons of acetic acid in carbon tetrachloride, benzene-<I>d</I><SUB>6</SUB>, and chloroform-<I>d</I> in order to investigate the effect of the self-association of acetic acid on the spin-lattice relaxation. It was found that there exists a maximum of the relaxation rate in carbon tetrachloride, and two maxima in benzene-<I>d</I><SUB>6</SUB> and chloroform-<I>d</I>, on dilution with a solvent. This relaxation behavior was attributed to the change in the self-association mechanism of acetic acid. We tried to keep the proton-density constant in all solution in order to avoid any ambiguity arising from the change in density by using the analogous deuterated compounds.
