Abstract
Recent investigations of the broadening and shift of isotropic Raman lines of compressed hydrogen have demonstrated the effects of intermolecular forces on intramolecular motions. This paper describes two cells suitable for such experiments in the low to medium density range. The first is a cell for use at 85°K and 100 atm, which is similar in design to a conventional Raman source. The second cell, for use at room temperature and at pressures up to 1000 atm, utilizes the large compressive strength of glass and is an improved version of a cell reported previously. High resolution Raman spectra of the Q1 branch of hydrogen have been obtained in the range 25 to 400 times standard density both at liquid air and room temperature.
