Abstract
Dielectric response in methanol measured in wide pressure and temperature range ( GPa; 100 K 360 K) reveals a series of anomalies which can be interpreted as a transformation between several solid phases of methanol including a hitherto unknown high-pressure low-temperature phase with stability range 1.2 GPa K. In the intermediate P-T region GPa K a set of complicated structural transformations occurs involving four methanol crystalline structures. At higher pressures within a narrow range GPa methanol can be obtained in the form of fragile glass ( K, at GPa) by relatively slow cooling.
