Impurity induced first order Raman spectra are presented for thallium doped CsCl and CsBr. The results of a Green's function calculation assuming that only nearest neighbor motion contributes to the Raman scattering are reported and compared with experiment. It is possible to separate the spectral contribution to the Raman scattering from each of the four symmetry coordinates. A reversal is found of the intensity ordering of these contributions when comparing the present results for positive impurities to previous results for negative impurities.
