Pressure Effects on the Vibrational Modes of K2PtCl4, K2PdCl4, K2PtCl6, and K2PdCl6

摘要

Pressure effects on the vibrational modes (internal and lattice) of tetragonal crystals of K2PtCl4and K2PdCl4were studied. The most pressurehyphen;sensitive external mode for these compounds was the translational mode along the long axisa0, while the least sensitive was the translational mode along the short axisc0. Results with cubic crystals of K2PtCl6and K2PdCl6showed that the lattice mode demonstrated higher pressure dependency than the internal modes.
