XRD, FTIR, ¹H NMR, ¹³C NMR and UV spectroscopic and computational studies of [3-(hydroxyimino)butan-2-ylidene]furan-2′-carbohydrazide

<p>[3-(hydroxyimino)butan-2-ylidene]furan-2′-carbohydrazide (1) has been synthesized and characterized by IR, 1H NMR, 13C NMR, UV/vis and X-ray diffraction. In addition to the experimental studies, the optimized structure, vibrational parameters, chemical shifts, thermodynamic properties, ionization energy, electron affinity, electronegativity, global chemical hardness and chemical softness of the molecule have been investigated by using DFT with B3LYP/6.311G(d, p) and PBEPBE/6.311G(d, p) basis sets. HOMO and LUMO energies were calculated by TD-DFT approach in two different solvents. The experimental results of the compound have been compared with theoretical results and it is found to show good agreement with calculated values.</p
