Implication for high-pressure silver halide chemistry

Abstract

In this short contribution, we examine Raman spectroscopic data from high-pressure and high-temperature experiments with Ag-Cl$_2$ system, and find that they are in good agreement with previously observed and calculated spectra of polychloride species. Our results imply the formation of a hitherto unknown AgCl$_x$ compound, which warrants further study.
