The Raman effect in topaz and its relation to the luminescence spectrum
The Raman effect in topaz has been investigated using the 2536·5 mercury resonance radiation as exciter. The spectrum exhibits 32 Raman shifts of which no less than 21 have been recorded for the first time. The results obtained axe discussed with special reference to the infra-red absorption tion and luminescence spectra of topaz. The significance of the complete correspondence noticed between the Raman shifts and the frequency shifts of the vibrational bands in luminescence is pointed out.
