Cryogenic apparatus for diffuse reflection infrared spectroscopy with high-pressure capabilities

Abstract

A cryogenic apparatus for obtaining diffuse reflection infrared spectra at liquid helium temperature is described. The system combines a commercially available reflection accessory and cold finger cryostat with a custom designed vacuum housing and high-pressure sample cell. This enables spectra to be obtained from room temperature to 10 K and at gas loading pressures as high as 100 bars. Initial experiments on H2 in solid C60 show the power of the system to obtain spectra that are significantly enhanced relative to those at room temperature.
