文摘
- •
Raman spectroscopy, synchrotron XRD and ruby fluorescence technique have been employed to investigate [HMIM][BF4] under high pressure.
- •
[HMIM][BF4] undergoes two successive disorder to disorder phase transitions under high pressure up to 20 GPa.
- •
Conformational equilibrium of [HMIM][BF4] is altered in liquid and not influenced in glassy state.
