MODULATORS :: APPLICATIONS :: Polarization Modulation Infrared Reflection-Absorption Spectroscopy (PM-IRRAS) 

PM-IRRAS stands for Polarization Modulation Infrared Reflection-Absorption Spectroscopy. It is the differential IR absorption between the s- and p-linearly polarized light for the molecules adsorbed on a metal surface.

SETUP



PEM setting: half-wave retardation (/2)
Polarization modulation: between s-, and p- polarization
Lock-in reference: PEM’s 2nd harmonic (2f)

TYPICAL PEMs
II/ZS50
II/ZS37
