Orientational behavior of naphthalene-d8 dissolved in nematic solvents

Symmetry of van der Waals molecular shape and melting points of organic compounds

“…Many theoretical schemes that utilize molecular shape factorisation were applied in studies of condensed phases (see e.g. refs [26][27][28][29][30]. Particularly close to our approach is the surface tensor model suggested by Ferrarini et al 28,29 where molecular potential in a liquid crystal was expanded into modified spherical harmonics and integrated over a molecular surface composed of atomic van der Waals spheres.…”

Prediction from Molecular Shape of Solute Orientational Order in Liquid Crystals

“…The initial work on zero electric field gradient nematic liquid crystals utilized the mixture 55 wt % 1132 and 45 wt % EBBA at 301.4 K. Studies were carried out on a collection of solutes of varying sizes, shapes, and symmetries, including solutes that exist in more than a single conforma- tion. 29,31,34,36,39,[43][44][45][46]55,58,60,62,67,70,76,79,87,92,[99][100][101][102][103][104][105][106][107][108][109][110][111] It was found that phenomenological models for the anisotropic short-range interactions provided the best rationalization of the experimental results, which will be summarized in section VIII.…”

An Orientational Study of Small Solutes in Zero Electric Field Gradient Nematic Liquid-Crystal Mixtures

“…99, No. 18,1995 Table 3 for all solutes in both zero efg mixtures. To account for differences among sample tubes, k, is divided by the k', determined from TCB in the same sample tube.…”
