Abstract
Abstract A general scheme of quantitative Raman analysis has been developed which avoids to a large degree the effects of sample composition and various instrumental factors on the observed scattering coefficients. Measurements are made in solution with a perpendicular Polaroid filter around the sample. The solvent is used as an internal standard. Band intensities are measured above a linear base line to correct for background. The method provides for the effects of partial polarization of the Raman radiation and for changes in the relative spectral sensitivity. Samples which are colored or fluoresce excessively cannot be analyzed by this method.
