Abstract
Gas-chromatographic experiments were carried out in various phases of the solvents 4-acetoxy-N-[4-methoxy-benzylidene]-aniline, dibutoxyazoxybenzene, lithium stearate, dihexoxyazoxybenzene, and diheptoxyazoxybenzene. The solutes were linear, branched and cyclic alkanes, and substituted benzenes. Excess enthalpies, entropies, and free entropies were calculated from net retention volumes. In the nematic liquid crystalline phases the effect of order disturbance was significant in\(\bar H_2^e\) and\(\bar S_2^e\) but it was, by enthalpy-entropy compensation, not demonstrable in\(\bar G_2^e\). Differences in flexibility and degree of expansion of the solutes did not result in significantly different values of the excess quantities.
