Translational correlation function of interaction-induced dipoles in dense media

Abstract
The time-correlation functions associated with the translational motions of the dipole—induced by permanent multipoles of an arbitrary order 1=1,2,3,...—in a dense fluid have been calculated analytically assuming the isotropic diffusion mechanism. The correlation functions obtained from this model have been compared with the available results of the molecular dynamics simulations in liquid N2 (T=75.5 K, ρ=0.814 g cm−3) and CS2(T=298 K, ρ=1.26 g cm−3) and appear to reflect the proper time scale of the relaxation process.
