Abstract

The H-1 and H-1 NMR spectroscopy of the nematic liquid crystal ZLI 1132 containing small amounts of the solutes 1,3,5- trichlorobenzene. p-dichlorobenzene and acetone was investigated as a function of the pressure of a mixture of molecular hydrogen and deuterium gases above the sample. A general increase of solute orientational order with pressure was observed. Differences in behavior of the orientational order of the hydrogens compared to the other solutes are discussed.
