Molecular motions in liquid. I. Rotation of water and small alcohols studied by deuteron relaxation. Fung, B. M.; McGaughy, Tim W. (Dep. Chem., Univ. Oklahoma, Norman, Okla., USA). J. Chem. Phys., 65(8), 2970-6 (English) 1976. CODEN: JCPSA6. DOCUMENT TYPE: Journal CA Section: 65 (General Physical Chemistry) The deuteron spin lattice relaxation time T1 of CH3OD, C2H5OD, (CH3)2CHOD, and (CH3)3CHOD is reported as a function of temp. and frequency. The deuteron T1 of the alcs. in dil. benzene solns. was also measured at 25.degree.. A detailed anal. of the exptl. results and other magnetic and dielec. 925-93-9 and 3979-51-9 are also in the experiment. relaxation data from the literature was made. Based upon the anal., it is suggested that the success of the Debye model in explaining the dielec. and magnetic relation behavior of water and small alcs. may be purely coincidental. It seems that the error in applying Stokes law for the rotation of a macroscopic sphere to small mols. in liq. and the error in assuming that water and alcs. rotate as monomers largely cancel each other, yielding much better apparent agreement between calcd. and exptl. data than those for nonassocg. liqs. The deuteron T1's for the alcs. are further analyzed in terms of anisotropic rotation. .
