Abstract
The vibrational spectra of the cooperite type compounds PdO and PtS (space group P42/mmc - D4h 9, Z = 2) are analyzed. Good agreement between experimental and calculated lattice vibration frequencies is obtained using a force field which includes short-range force constants only. This demonstrates a highly covalent bonding character of the cooperites.Keywords
