Abstract
For Raman spectroscopy of gases, intense illumination is required. The relatively low tensile strength of transparent materials has always severely limited such studies at high pressures. This paper describes a method by which use is made of the very high compressional strength of glass. The essence of the method is that the compressed gas is contained in an enclosed space outside a thick‐walled glass tube; inside the tube a water‐cooled mercury lamp is inserted. Pyrex tubes of 0.5 in. i.d. and 0.75 in. o.d. thus withstand pressures in excess of 3000 atm. The scattered light is observed through a conventional self‐sealing window. High resolution Raman spectra have been obtained, for various simple gases, at pressures up to 2500 atm.Keywords
