Summary

The Raman spectrum of quartz has been studied at a series of nine temperatures from 85° to 685°K. Data regarding the variations in frequency shiftdv, breadth and the proportional changed logv/dT are furnished for twelve of the important Raman lines of quartz. The proportional change is found to decrease progressively with the frequency shift of the Raman line, being highest for the low frequency lines and lowest for the high frequency ones. The temperature-frequency shift and the temperature-width curves for the individual Raman lines show similar characteristics, tending to flatten up at low temperatures and the rate of change being greater at high temperatures. The peak intensity of the Raman lines is also found to decrease markedly with rising temperature.
