The combining nuclear magnetic resonance techniques in the solid state permit the evaluation of the polymeric systems homogeneity. In the polycarbonatepoly(vinyl pyrrolidone) (PVP) blends, the response of proton spin-lattice relaxation time in the rotating frame was the determinant to obtain informa

Abstract
High‐resolution solid‐state ^195^Pt NMR spectra of ammonium, potassium and sodium hexachloroplatinate(IV) and its hydrate were investigated using magic angle spinning of the sample. The isotropic part of the spectra has fine structure originating from dipole–dipole interaction and indirect spin coupling between platinum and chlorine nuclei. The fine structure was analysed theoretically, yielding the indirect spin coupling constants and their anisotropies.
