Abstract

In the course of a vibrational study of methanetellurol (CH3TeH) a need arose for a short path (approximately 10 cm) it gas cell which uses no stopcock grease, no wax to seal the windows, presents a relatively inert inner surface, and can be rapidly assembled and disassembled. These requirements arise from the fact that methanetellurol and many similar compounds are unstable, decompose, and/or absorb readily in the presence of active surfaces, stopcock grease, and sealing wax. These materials are generally used in the construction of conventional cells, particularly the homemade variety, and their presence often accounts for experimental difficulties. There are several commercially available cells which partially meet these requirements but all of these have some undesirable features, such as ground glass stopcocks which require silicone or hydrocarbon grease. Therefore, we have devised and wish to describe a fairly inexpensive cell which meets the above specifications.
