Abstract
Raman scattering from zinc sulphide crystals containing a transition metal substitutional impurity (Mn and Co) is reported at different pressures up to 40 kbar. Numerical calculations of these impurity induced Raman intensities are also made on the basis of Green's function theory. It is shown that the features observed in the Raman spectra of the above crystals may be interpreted as a series of resonant modes due to the weakening of the impurity-sulfur bonds by about 20 %.
