Abstract

A standard intensity scale for Raman bands in liquids has been proposed which is referred to the Raman band at 458 cm⁻¹ in CCl₄ taken under the same experimental conditions. Standard intensities are obtained from the photoelectrically registered spectra by correcting for convergence error, spectral sensitivity of the photomultiplier tube, optical density of the sample and reflection loss, and reduction to scattering per molecule. In all cases integrated intensities are used. Calculation of the effect of a triangular slit function on a Lorentz type Raman contour yields correction factors for converting the product of the peak intensity and the observed half band width to integrated intensities. Standard intensities are given for the Raman bands of liquid CH₂Cl₂, CHCl₃, and CCl₄. The apparent departure of the intensity from its linear dependence on concentration is also discussed.
