The 10 and 300 K Raman spectra of CdBr, and CdClz have been investigated at high sensitivity. While some of the new lines are of second-order origin, others are associated with local modes of halogen impurities. Lines at 107 and 170 cm-' in CdBr, are assigned to the EJTO) and A,,(TO) lattice modes r

โฆ Synopsis
The Iow-lying electronic energy levels of the divnlcnt colx~it ion in doped isomorphic single crystals of CdC12, CdBr2 nnd MnClZ have been measured at low temperatures by means of the Lkxtxm effect. 'She observed energies, which arc markedly concentration dcpcndent, arc ussigned to transitions within the 4i? ground-state manifold oE Co2* with the aid of crystal-field theory.
