Abstract

A sample cell and optical mount for use in laser Raman spectroscopic studies of adsorbed species at elevated temperatures is described. In situ Raman spectra of pyridine adsorbed on 60–120 mesh silica gel at room temperature, 75 °C, and 150 °C are reported. The cell has also been used in studies of other species adsorbed on silica, alumina, and platinum wire.
