Abstract
An important yet unsolved problem in the field of orientational relaxation in dipolar liquids is the dependence of the correlation functions Cl(t), Cl(t) = [4π/(2l + 1)Σm = -1l [Y*lm(Ω(0)Ylm(Ω(t))] on the rank l (where Ylm(Ω) are the usual spherical harmonics). The existing theories on this effect differ in their predictions. To investigate this, we have carried out extensive computer simulations of a Brownian dipolar lattice. The dielectric friction was found to decrease rapidly with increasing l, in qualitative agreement with the predictions of Hubbard-Wolynes. However, the observed effect is much stronger than the predictions of the existing theories.
