Summary
The Raman spectra of borax, (Na2B4O7·10H2O), kernite (Na2B4O7·4H2O) and colemanite (Ca2B6O11·5H2O) have been investigated using λ 2536·5 as exciting radiation. The spectrum of colemanite is reported for the first time. Many additional lines hitherto unreported have been found in the case of kernite and borax. The spectrum of borax exhibits seven lines, besides four bands due to water of crystallisation while the spectrum of kernite is found to consist of twenty-eight lines and six water bands. Colemanite exhibits nineteen Raman lines, and three bands due to water of crystallization. The observed spectra are discussed in relation to the known structures of the substances.
