Abstract
A method utilizing divided KBr discs has been developed for estimating the relative intensities of the resonance Raman bands of different samples in the solid state. The relationship between the band intensity and the sample concentration in the disc is described on the basis of the Kubelka‐Munk theory of diffuse reflection. The utility of the method was checked by using crystalline methyl orange and potassium sulphate as the sample and reference materials, respectively. By comparing the measured and calculated intensities, the Raman scattering coefficient of the NN stretching band of methyl orange at 1420 cm−1 was estimated to be 440±90 times as large as that of the 984 cm−1 band of potassium sulphate.
