摘要: High pressure Raman spectroscopic studies on perfluorohexane and perfluoroheptane have performed up to 12 GPa. Perfluorohexane under goes two induced transitions: (1) liquid-solid transition at 1.6 GPa (2) solid-solid 8.2 On the contrary, three phase transitions, they are as follows: 1.3 GPa, intermediate solid I 3 (3) II 7 The change in slope (d omega/dP) shows that 3.0 could be conversion of mid-gauche defect into trans conformers for perfluoroheptane. spectra behavior individual band with comprises more than one conformer beyond crystallization. intensity ratio both compounds high 7.0 tends close packing distorted all-trans conformers.
