| 摘 要： | Effects of orientational pair correlations on the reorientationrate of non-spherical molecules are studied.The Keyes-Kivelsonequation for the coherent light scattering relaxation time isderived using a different technique.Experimental data on thecoherent light scattering relaxation time and the single parti-cle reorientation for n-butanol are obtained as a function ofthe concentration of n-butanol.The results are compared withthe Stokes-Einstein-Debye equation and are discussed in termsof the orientational pair correlation effect.
