Abstract

The solvation shifts over a wide range of temperatures and pressures were estimated. Quinoline was chosen as a probe to quantify the interactions. Solvatochromic shifts in the π-π* absorption band of quinoline show a strong relationship between hydrogen bonding and other solute-solvent interactions in supercritical wave. The degree of hydrogen bonding between quinoline and water decreased with increasing temperature.
