The plant investigated has been found to contain at least five alkaloids, three of which, l-sparteine, d-lupanine, and d-α-isolupanine, are of known structure. The remaining two are both isomeric with hydroxylupanine. One of these, lupilaxine, was identical with a base previously reported as occurring in Lupinuslaxus. The other, lupanoline, appeared to be new. Both these alkaloids were shown by their infrared absorption spectra to contain, like hydroxylupanine, one hydroxyl group and one carbonyl.

A method is described for the purification of two phenazine compounds from cultures of a strain of Pseudomonas aureofaciens. The chemical properties of the compounds are described and the ultraviolet, visible, and infrared absorption spectra are shown. One compound is identified as phenazine-1-carboxylic acid and the other is probably 2-hydroxyphenazine-1-carboxylic acid.

FTIR spectra of homologous series of monohydric alcohols which belong to the class of partly ordered liquids were registered. The molecules of monohydric alcohols containing hydroxyl group are able to form hydrogen-bonded clusters in the condensed phase. The existence of clusters is clearly observed from the position and the contour of the stretch OH band in the vibrational spectra of liquid alcohols. In this work, the experimentally registered FTIR spectra of liquid n-alcohols from methanol to decanol are presented as well as the same spectra of methanol, ethanol, propanol, butanol, pentanol, and hexanol in gas phase.

The crystal structures of (C6H5)4AsBF4, (C6H5)4AsPF6, (C6H5)4AsAsF6, and (C6H5)4AsSbF6 have been studied by X-ray diffraction. The unit cells are all tetragonal. The fluoroborate compound is probably isostructural with (C6H5)4AsFeCl4. The other three compounds are almost isostructural with (C6H5)4AsFeCl4, the only change being the accommodation of the dipyramidal PF6− ion in the space group [Formula: see text] (No. 82). Infrared absorption spectra are in general agreement with previous work on tetraphenylarsonium halides and compounds with hexafluoro Group VA ions. It is concluded that crystal field effects for this series of salts do not markedly affect the vibrational spectra.
