Combining ionic liquids and supercritical fluids: in situ ATR-IR study of CO2 dissolved in two ionic liquids at high pressuresElectronic supplementary information (ESI) available: schematic view of the miniature high-pressure flow cell. See http://www.rsc.org/suppdata/cc/b0/b005514j/

Abstract

An in situ ATR (attenuated total reflectance)-IR study of CO₂ dissolved in two ionic liquids at high pressures has demonstrated the effects of the anionic species of the ionic liquids on the molecular state of the dissolved CO₂.
