Photometry of Raman spectra of crystals

Abstract

Using the ultra-violet Spekker photometer and the resonance radiation of mercury as exciter the relative intensities of the Stokes and anti-Stokes Raman lines in the case of calcite, quartz, barytes and ammonium di-hydrogen phosphate have been measured. It is found that the results obtained confirm the theoretical relation that the intensity is proportional to the fourth power of the emission frequency. The new method outlined in this paper makes it possible to measure the intensity ratios in case of high frequency shift Raman lines.
