Self‐Diffusion Coefficients and Rotational Correlation Times in Polar Liquids

摘要: Self‐diffusion coefficients and rotational correlation times have been measured in several polar liquids by pulsed nuclear magnetic resonance techniques. Diffusion were for HCCl3, ClC6H5, HF, HCl relaxation HF. The self‐diffusion coefficient of a liquid is related to the time τ2 means quasilattice model liquids. diffusion equation Stokes–Einstein expression are inadequate respectively replaced results large‐step random‐walk theory an based on model. An τ2, obtained from dynamical coherence theory, shown not apply case spherical‐top molecule CCl4 which would be anticipated small friction constant. correspondence between calculated values observed is...
