The quadrupolar splittings of deuteriated para-and ortho-dichlorobenzene (1, 4-DCB and 1, 2-DCB, respectively) are measured by nuclear magnetic resonance (NMR) in the nematic solvents hexyl-and pentyloxy-substituted diphenyl diacetylene (DPDA-C6 and DPDA-OC5, respectively). Measurements are taken for all four combinations of the nominally apolar (1, 4- DCB) and polar (1, 2-DCB) solutes in the apolar (DPDA-C6) and polar (DPDA-OC5) ...
