heal.abstract	Mixed valence-mixed metal compounds of platinum and palladium are complicated ionic crystals containing independent parallel chains, and a linear unit cell of four masses containing both Pt and Pd - each in a given state of oxidation II or IV. The natural vibrations of such systems contain longitudinal lattice modes and almost independent local modes. Their Raman spectra contain indistinguishably the frequencies of both kinds of modes. A study of these vibrations requires some method of distinguishing unambiguously between these two kinds of modes, not presently available. We present here a detailed study of the longitudinal lattice modes. Our study develops criteria for distinguishing with some certainly between the two kinds of modes and we assign accordingly their observed Raman frequencies. Furthermore, we propose a method for their unambiguous distinction by performing Raman spectroscopy on a disordered version of these compounds. © 1980.	en
