The Raman spectroscopy of bromide- and chloride-bridged platinum linear chains under isotropic pressure reveals an initial hardening and subsequent softening of the symmetric halide stretching mode as pressure is increased. These results reflect an initial increase in the extent of the metal sublattice charge disproportionation (charge density wave, CDW) followed by CDW weakening and are consistent with previous absorption studies of the band gap. Phase changes that are independent of the CDW strength occur for both materials near 2.5 and 4.5 GPa and, at least for the lower pressure transition, may be due to an indirect effect that leads to interchain ordering.
