    Abstract:
    Crystallographic, experimental (FT-IR and FT-RS) and theoretical density function theory (DFT) and UV-Vis spectra of (E)-1-[1-(4-Chlorophenyl)ethylidene]thiosemicarbazide) (ECET) are investigated. The optimized geometry of the compound was calculated from the DFT-B3LYP gradient calculations employing 6-31G (d,p) basis set and calculated vibrational frequencies are evaluated via comparison with experimental values. Molecular stability has been analyzed using Natural Bond Orbital (NBO) and Natural Localized Molecular Orbital (NLMO) analysis and the limits of the molecular electrostatic potential observed. The calculated HOMO and LUMO energies show the charge transfer occurs within the molecule.
