ORIENTATIONAL CORRELATION PARAMETER FOR LIQUID CS2, C6H6 AND C6F6

The values of the second rank orientational correlation function gt and the effective polarizability anisotropy of liquids CS2, C6H6 and C6F6 were determined by combining data from the Rayleigh spectrum with Cotton-Mouton measurements on these liquids in a way which avoids difficulties with the interaction-induced polarizability. A detailed discussion of the errors associated with this procedure is presented. The values are used to interpret the Kerr constants of these liquids. The value of g2 is combined with Rayleigh and Raman reorientational relaxation times to determine the dynamic orientational correlation parameter. Comparison with previous values suggests the plausibility of calculating the effective polarizability in a dielectric model. © 1979 Taylor & Francis Group, LLC.
