The effect of optical polarization on reflection spectra.
The theoretical basis for polarization effects in reflection spectra are reviewed. It is shown that light polarized parallel to the plane of incidence interacts more strongly with the absorbing species than does light of perpendicular polarization except under conditions of internal reflection when the absorber is a thin film between two nonabsorbing media. In this instance the relative degree of interaction is determined by the refractive indices of the three phases. Experimental results are presented which show the predicted effects for internal reflection spectroscopy both when the absorbing medium is a solution of (CH(3))(4)NCl in D(2)O and when it is a monolayer of stearic acid.
