Abstract The Raman spectra of SbSBr, BiSI, SbSeI, and BiSeI are investigated and compared with those of SbSI. Following the analysis of each observed mode from one substituted compound to another, a set of normal mode functions is proposed to account for the overall spectral feature of these compounds. The results are then tentatively interpreted in terms of the mass change based on a semi‐ionic model. It is shown that the agreement with experimental data is excellent for the system SbSBrSbSIBiSI. In the contrary, a serious discrepancy exists in the SbSeIBiSeI system suggesting that the binding of sulfur and neighbouring atoms is substantially affected by the SSe substitution in these compounds.
