Paper Abstract

For transmission FT-IR spectroscopy of ultrathin films, we have developed a new double beam approach based on the technique of polarization modulation. Simultaneous recording of sample and reference interferograms makes detection insensitive to atmospheric (CO2, H2O) and substrate absorptions. In situ spectra of ultrathin films are obtained in a few minutes with high signal-to-noise ratio (S/N).
