## Abstract Topiramate is a white crystalline solid with powerful anticonvulsant activity and is used to treat epilepsy. Drug manufacturing involves various physical and chemical processes, which may lead to the formation of an unexpected, or undesired, crystalline phase, in a phenomenon known as p

Zn 1-x Fe x Se, x = 0, 0.018, 0.035 and 0.16, were studied by Raman scattering spectroscopy up to 35.0 GPa. It was found that the semiconductor-metal phase transition pressures for these samples are 14.4, 12.8, 12.0 and 10.9 GPa, respectively. Before the semiconductor-metal phase transition, a visib
