Polarized IR and Raman spectra have been measured for meta-dinitrotetramethylbenzene single crystals. Using different scattering and polarization geometries in the Raman effect and polarized reflectance and transmission infrared spectra, all the polarizability tensor matrix elements and electric dipole moment variations have been determined for the monoclinic crystal of this molecule. Lifting of degeneration, at the Brillouin zone center, of the longitudinal and transverse components of the infrared phonons have been detected and attributed to long range electrostatic interactions of the molecules in the unit cell.
