A New Technique

In total reflection spectroscopy the effective sampled depth increases as the angle of incidence approaches the critical one. At each angle of incidence, successive layers within the sample are weighed differently in the overall spectrum, and the manner of this weighing changes with angle. It is thus possible in principle to deconvolute a set of spectra taken at different angles into spectra corresponding to successive depth invervals. As this angular effect is particularly marked near the critical angle, where attenuated total reflection spectra are severely distorted, the spectra usually require inversion into optical constant spectra. This has been done by a new technique that measures spectra twice at each angle with different prism materials to give the necessary data sets. Examples of such subsurface spectra are shown.

Perpendicular Polarization

Attenuated Total Reflection infrared spectra were obtained for rough and spheroidal powders made from an amorphous polymer. The spectra were recorded with a polarizer to obtain both parallel and perpendicular components of the spectra separately. The results were compared to both theoretical predictions and experimental results for the same material examined as a film. It was found that the relative absorption intensities of the two polarization spectra recorded of the film agreed well with the theory for films. However, the powdered samples showed unexpected increases in absorption intensities for the perpendicular spectra. The intensities of the absorptions for perpendicular polarization were about 45% greater than for films as measured by the ratio of relative effective thicknesses. Implications for interpretation of the spectra of powdered materials are discussed.
