Substitution of O in the ZnS lattice is observed to result in a doublet consisting of two local vibrational modes (LVMs) and a second order harmonic of the LVMs. The first order doublet is attributed to vibrational modes of a defect with trigonal ( C 3v ) symmetry. The results of temperature dependent resonant Raman scattering and anti‐Stokes scattering support this assignment. The substitution of O in the lattice also leads to the presence of LVM + n LO combination modes, which are interpreted in terms of the cascade model and resonance effects.
