摘要
Infrared spectroscopy studies of 5-methyl-7-methoxy-iso-flavone in 20 different pure organic solvents were undertaken to investigate the solvent-solute interactions and to correlate solvent properties such as the Kirkwood-Bauer-Magat (KBM) equation, the solvent acceptor number (AN) and the linear solvation energy relationships (LSER), respectively, with the infrared band shift. Little linear relation between dielectric constants and the frequencies showed that the KBM relationship was unsuitable for the complicated molecules. These frequencies exhibited a better correlation with the LSER than the solvent AN. (C) 2002 Elsevier Science B.V. All rights reserved.
