摘要：

High-pressure Raman spectra of liquid and crystalline CHF2Cl and CHF3 were measured up to pressures of 15 and 10 GP&, respectively, at 300 K in a gasketed diamond-anvil cell. The liquid-solid phase transition pressures were determined to be 3.49 GPa for CHF2Cl and 2.46 GPa for CHF3. For both CHF2Cl and CHF3, the wavenumbers of the C-H stretching mode nu1 increased rapidly with increasing pressure, and this behaviour was investigated by the theory of reasonance hybrid of the covalent-bonded and ionic-bonded structures.
