Far-IR diln. measurements on DMF in carbon tetrachloride provide data on which to base an assessment of the way in which both the short-ranged and long-ranged dynamics are dependent on the surrounding mol. interactions. While there is an obvious increase in the rate of the long-time reorientational motion on diln., the short-time dynamics appear to be relatively weakly affected. This is considered to be due to competing effects of removal of solute-solute interactions and the addn. of solute-solvent interactions. The data are interpreted with the aid of the Gaussian-cage model of Lynden-Bell and Steele, which reflects the large intermol. mean-squared torques and the collective intermol. dynamic origins of the high-frequency spectral d. in the region of 80-120 cm-1.
