Raman spectra of dolomite [CaMg(CO3)2]

Abstract

The energies and symmetries of the even-parity phonons in CaMg${\left(\mathrm{C}{\mathrm{O}}_3\right)}_2$ have been determined and compared with theory. A simple model calculation explains the very weak intensities of three $A_g$ modes which would be $A_{2g}$ and Raman forbidden in isomorphic calcite.
