Raman Spectroscopy in Ionic Liquids Under Variable Thermodynamic and Environmental Conditions

摘要: The potentialities of the Raman spectroscopy in providing a deep insight into microscopic anion-cation interactions ionic liquids are discussed. We report on and discuss measurements mainly collected particular class called protic (PILs), based nitrate anion, NO3 −. Together with spectroscopic investigation, first principle studies have been carried out for most measured samples. combined experimental-theoretical approach allows us to deeply investigate effects induced by length alkyl chain optical properties PILs. also focus systematic temperature (300–450 K) pressure (0–10 GPa) dependent studies. extended P–T region explored observe liquid–solid several solid–solid transitions draw general remarks phase diagram Finally, exploiting high sensitivity protein secondary tertiary structures, efficacy PILs as refolding enhancers is
