The binary mixtures of 6OCB and 8OCB exhibit reentrant nematic behavior over a narrow range of compositions. We have studied a mixture having 27.12% of 6OCB by weight by neutron scattering technique. The experimental intensity values I(Q) are fitted with a Lorentzian function. From the fitted parameters we have calculated the short-range correlation length (xi) perpendicular to the director ((n) over tilde) and the intermolecular distance (D) throughout the mesomorphic range. The results are discussed.
