Raman spectra of synthetic "braggite", (Pd,Pt,Ni)S

Raman spectra of synthetic "braggite" (Pd, Pt, Ni)S) vary systematically with changes in Pt/Pd ratios, but this change is less pronounced than in "cooperite" ((Pt, Pd, Ni)S). Compared to "vysotskite" (ideally PdS), the incorporation of Pt leads to broadening of bands but the spectra of "vysotskite" and "braggite" are similar, and spectra of "cooperite" and the "braggite/vysotskite" solid-solution series are sufficiently different to facilitate distinction of these platinum group minerals by Raman spectroscopy.
