|Abstract:||The Fourier transform infrared (FT-IR) spectra of four coloured beryls, both in single crystal and powder form, were studied at room temperature to characterize the volatile constituents of beryls from Badmal mines of Orissa state, Among the four coloured beryls (colourless, blue, green and yellow), the green beryl shows predominance of type-II H2O. Presence of sodium and cesium molecules associated with OH- group and CO2 as common channel constituent is also deciphered. Fourier self-deconvolution (FSD) technique is applied to observe weak shoulders and classify beryls based on substitution. While the c/a ratio of 0.9994-0.9996 indicates beryls to be of 'tetrahedrally substituted', the FT-IR study in the structural vibration indicates them to be of 'normal type'.|
