dc.description.abstractSpectroscopic and structural investigations of 3,4-difluoroaniline molecule are presented by using experimental (FT-IR, FT-Raman, H-1 and C-13 NMR, and UV-Vis) techniques and theoretical (DFT approach) calculations. FT-IR and FT-Raman spectra of 3,4-difluoroaniline molecule are recorded in the region 4000-400 cm(-1) and 3500-10 cm(-1) in the liquid phase, respectively. The NMR chemical shifts (H-1 and C-13) are recorded in chloroform-d solution. The UV absorption spectra of 3,4-difluoroaniline dissolved in ethanol and water are recorded in the range of 200-400 nm. Experimental results are supported with the following theoretical calculations; the optimized geometry and vibrational (FT-IR and FT-Raman) spectra are carried out by DFT (B3LYP)/6-311++G(d,p) basis set calculations. The nuclear magnetic resonance spectra (H-1 and C-13 NMR) are obtained by using the gauge-invariant atomic orbital method. Moreover, electronic characteristics, such as HOMO and LUMO energies, density of state diagrams, and molecular electrostatic potential surface are investigated. Nonlinear optical properties and thermodynamic features are also outlined theoretically. An excellent correlation of theoretical and experimental results provides a detailed description of the structural and physicochemical properties of the molecule. Thus, this work leads to a deep understanding of the characteristics of di-substituted aniline derivatives. (C) 2015 Elsevier B.V. All rights reserved.
