Raman spectra of bis(diphenylglyoximato) metal complexes M(dpg)(2) (M = Pt and Ni) under high pressure have been studied. The C = N stretching bands remarkably moved with increasing pressure. The relationship between the Raman shift and pressure is almost linear. The rates of increase in the Raman shift with pressure were determined. The platinum complex was more sensitive to pressure than the nickel complex, which is consistent with the pressure dependence of absorption spectra. The shear stress effect applied on the Pt(dpg)(2) thin film was quantitatively estimated by using the relationship between the Raman shift and pressure.
