The gas chromatographic properties of the smectic and nematic mesophases of four well-characterized liquid crystals are reported\_ Selectivity and resolution of anthracene and phenanthrene is greater at column temperatures corresponding to these liquid crystals' smectic A and smectic C phases than a
## Abstract A gas‐chromatographic separation of underivatized steroids is described, in which the liquid crystal N,Ń‐bis(p‐phenylbenzylidene)α,α′‐bi‐p‐toluidine (BPhBT) was used isothermally at 265°C for the stationary phase. The nematic range of this crystal is 247 to 403°C. Use of the BPhBT cryst
