The spectral characteristics, and solution conditions requisite for formation, of the iron(II), cobalt(II), and copper(I) chelates of some newly synthesized oximes containing the ferroin functional grouping have been determined. For some of the oximes, both syn- and anti-isomers were available for study. NMR spectra of the isomers differed, enabling structural distinctions to be made. None of the anti-isomers formed coloured metal chelates. A practical method for distinguishing between the isomers can be based on these findings. Two of the compounds proved very promising as highly sensitive chromogens for determining iron in strongly alkaline materials.

Gas-chromatographic properties were determined using a homologous series of carboxylic acid esters of cholesterol as stationary phases and several homologous series of organic species, having different functional groups, as volatile solutes. In general, the capacity ratios for the various solutes increased upon application of an electric field. On a relative basis, the change with potential was larger for solutes having smaller capacity ratios, for solvents having a longer acyl chain length of the liquid crystal, and for a faster carrier-gas now rate.

Reversible changes in gas-chromatographic peak shape and retention time were produced by applying an electric field across a capillary column that employed a liquid crystal as a stationary phase. In general, applied potential caused peaks to be retained longer and to be more nearly symmetrical in shape. The behavior of a variety of substances has been studied over a range of temperatures.
