摘要
The main attention of present work is to study how benzeneacetamide interacts with other molecules in organic solvents. The frequencies of CO groups in 18 solvents were obtained by using infrared spectroscopy. The empirical parameters of the solvents as the acceptor number (AN), the van der Waals interaction parameters (SVW) and the linear solvation energy relationships (LSER) were correlated with the frequencies of carbonyl stretching vibration (ν(CO)) of benzeneacetamide to estimate the contributions in intermolecular interactions. The results showed that solvent effects on the frequencies of CO stretching vibrations of benzeneacetamide were obvious. Self-association of alkanol leads to enhancement of O-H⋯O=C hydrogen bond strength and red-shift of the ν(CO) peak. The ν(CO) of benzeneacetamide is more vulnerable to the acidity of the hydrogen bond donor of the solvent. This research contributes to a thorough understanding of the molecular interactions and microstructures in the liquid mixtures.
