Abstract
The theory of local symmetry breaking by impurities and mode splitting in doped Sm1-xYxS was described. The Y impurity was found to change the local crystal-field environment of each Sm ion from cubic to tetragonal structure. The results showed that the Y impurities caused the observed mode splitting by breaking the local cubic symmetry about each Sm ion.
