FTIR spectroscopy has been in wide spread use for the detection and identification of the definitive 'fingerprints' of molecules for some time now. Most applications of FTIR spectroscopy have been limited to utilizing and interpreting mostly transmitted and reflected intensities either in terms of relative intensities or as circular dichroism changes. Thin films formed by biological molecules have thus been investigated and limited use of ellipsometric analysis made. The limited use mainly attributable to the limitations of the method as well as the esoteric theory and modeling required in interpreting the results. In our current work, we investigate the use of an attenuated total internal set up to perform IR ellipsometry on a few model biological molecules and present preliminary data obtained there off. Molecules of interest were chiefly human albumin, immunoglobulin and fibrinogen.
