Journal of Physics C: Solid State Physics, 1975 We present new measurements of the optical mode frequencies in AgGaS2, and suggest reasons why previous determinations are in error. The results indicate that AgGaS2 cannot be regarded as a small perturbation of a zincblende structure, but they are in accord with the predictions of a recent model calculation by Bettini.
