Paper Abstract

Infrared reflection-absorption spectroscopy is a technique that can be used to study molecules adsorbed in monolayer and submonolayer concentrations on low-area metal surfaces. The results from four experimental approaches, each involving polarized light reflected off flat metal surfaces at near-grazing angles of incidence, have been compared. The approaches are (1) an optical-null experiment on a double-beam dispersive spectrometer, (2) a fixed-polarizer experiment using FTIR, (3) a polarization-modulation single-heam experiment on a dispersive spectrometer, and (4) a polarization-modulation experiment using FTIR. A thin film of cellulose acetate on copper is examined. The polarization-modulation FTIR approach gives the best results for this system.
