CO 2 ‐philicity: The 13 C NMR chemical shift ( δ C ) of supercritical CO 2 containing carbonyl compounds moves to lower fields with increasing CO 2 density in parallel with the δ C value of neat scCO 2 . The difference in the magnitude of these shifts (Δ δ C ) is attributed to the strength of solute–CO 2 interactions (see picture, R=CH 3 or CF 3 , L=DMSO) and allows determination of the CO 2 ‐philicity of solute molecules in scCO 2 .
