Paper Abstract

We have obtained infrared emission spectra (600-2000 cm-1) from room temperature samples of reflective metal substrates with organic overlayers using a liquid nitrogen cooled interferometeroequipped with a liquid helium cooled Ge:Cu detector. Overlayer thicknesses as low as ≈10 Å have given good spectra. Spectra were obtained with a modified Digilab 14-B interferometer operating at 2 cm-1 resolution. The viewing angle of the sample was usually ≈55° from the surface normal and a polarizer was used in some runs to obtain improved signal to noise. The spectra were corrected for instrument response function, substrate background and thermal populations and emission efficiencies of excited vibrational states.
