摘要

Conformational, structural, vibrational spectroscopic properties and nuclear magnetic chemical shift values of 4-acetoxyphenethyl acrylate (4APA) were investigated using spectroscopic and theoretical approaches including FT-IR and NMR spectroscopes and quantum chemical calculations. FT-IR spectroscopic measurement was carried out between 3500 cm(-1) - 1400 cm(-1). Geometric parameters, vibrational wavenumbers and nuclear magnetic chemical shift values were estimated using B3LYP hybrid density functional theory method with 6-311++G(d, p) basis set. H-1, C-13, APT and HETCOR NMR experiments of 4APA were obtained in DMSO solution. For a quantitative description of vibrational wavenumbers, total energy distribution (TED) values with scaled quantum mechanical (SQM) method were calculated. Moreover, molecular docking study of title molecule was theoretically carried out using Auto Dock Vina Program.
