Abstract: We have investigated pressure-induced Raman spectral changes of ionic liquid, N,N-diethyl-N-methyl-N-(2-methoxyethyl)ammonium bis(trifluoromethylsulfonyl)imide ([DEME][TFSI]) up to 5.5 GPa. We found that the CH stretching spectrum of [DEME] cation changes significantly above 4 GPa together with the large shift of conformational equilibrium between C1 and C2 conformers of [TFSI] anion toward C2 one. The results along with the visual observations show that no crystallization occurs even at 5.5 GPa. We suppose that structural organization in [DEME][TFSI] might significantly change at 4 to 5 GPa region.
