reflection–absorption infrared spectroscopy
polarization modulation infrared reflection–adsorption spectroscopy
PM-IRRAS
Spectroscopy where the differential absorption and reflection of low incident angle p- and s-polarized infrared light by the surface molecules of a highly reflective or polished sample is measured. The ultra-thin layers on metal surfaces interact with the p-polarized component of light, but not with the s-polarized component.
