Abstract

Solvent-induced frequency shifts in the infrared spectra of isophorone (IP), 4-oxo-isophorone (OIP), and 2,6,6-trimethyl-4,4-(ethylenedioxy)cyclohex-2-en-1-one (TEDCH) have been studied in 20 different organic solvents. The carbonyl stretching vibration frequencies of IP, OIP, and TEDCH were correlated with solvent properties, including the solvent acceptor number (AN) and the linear solvation energy relationships (LSER). The correlation results indicated that the LSER are better for describing the solute-solvent interactions than the solvent AN.
