Özet

Infrared spectroscopy studies of 1,3-indanedione (ID) in 16 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), using the infrared band shift. The correlations were performed both symmetric and asymmetric band stretching. Poor correlation between dielectric constants and the frequencies in both symmetric and asymmetric C=O stretching showed that the KBM relationship was unsuitable for the molecule studied in this work. These frequencies exhibited a better correlation with the LSER than the solvent AN. The asymmetric C=O stretching was found in better correlation than symmetric. (c) 2005 Elsevier B.V.
