Solvents effect on infrared spectra of 1,3-indanedione in organic solvents
نویسندگان
چکیده
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. # 2005 Elsevier B.V.

The solvatochromism of fluoresceine and its derivatives was studied in solvents of different Hydrogen Bond Donor (HBD), Hydrogen Bond Acceptor (HBA), Donor Number (DN) and Acceptor Number (AN) by their UV-Vis spectra. Results showed that position, intensity and shape of absorption bands change with type of solvent. These changes can be rationalized by solvatochromic parameters such as ...

Introduction: Hearing loss is one of the most common occupational diseases. In most workplaces, workers are exposed to noise and solvents simultaneously, so the potential risk of hearing loss due to solvents may be attributed to noise. In this study we aimed to assess the effect of exposure to mixed aromatic solvents on hearing in the absence of exposure to hazardous noise. Materials and Met...
