5. Summary
The Raman spectra of fourteen different diamonds exhibiting diverse characters in their optical behaviour (viz., transparency in the infra-red and ultra-violet regions of the spectrum, birefringence and the intensity and colour of the luminescence) were recorded. The principal Raman line is found to have a frequency shift of 1331·7 ± 0·2 cm.−1 which agrees closely with the value of 1331·8 cm.−1 reported earlier. There were no observable variations in the frequency shift, width or intensity of the line in the several cases studied.
