摘要: Raman spectra of CaFe2O4 and Yb3S4 type compounds are sharp similar, indicating similar ordered structures. Spectra MnY2S4 exhibit three broad bands indicative structural disorder. ZnGa2S4 is an intermediate spectrum. There a linear relationship between the highest frequency IR average coordination numbers
