Abstract

Several low temperature infrared absorption cells have been described in the literature <i>(1-4)</i>. The simplest one of these, by Janz and Fitzgerald <i>(3)</i>, employs a sandwich cell surrounded with an aluminum foil housing and cooled with a liquid nitrogen reservoir. This cell, though well suited for obtaining spectra of non-volatile liquids at low temperatures, is not applicable for low boiling liquids. Two others <i>(1,2)</i>, though suitable for low boiling liquids, are of complicated design requiring precision workmanship. The low temperature infrared cell to be described is unique in that any of the commercial infrared liquid cell may be used as the base component. The cell is especially suited for the study of materials which are unstable at room temperature. Also it affords a means of obtaining the spectra of low boiling liquids without resorting to the comparatively expensive pressure cells.
