Abstract
3-Pyridinealdazine was synthesized and characterized by FT-IR, 1H, 13C NMR and mass spectroscopy. The conformations of azine was determined theoretically besides selected geometrical parameters, HOMO–LUMO energies, polarizability, hyperpolarizability, natural bond orbital (NBO), atomic charges, Mulliken charges and atom in molecule (AIM) analysis were also calculated. The optimized geometry of the symmetrical azine, HOMO–LUMO and molecular electrostatic potential (MEP) surface were also evaluated using B3LYP/6-31G(d,p) basis set. 13C NMR data were also computed using Gaussian-03 package and compared with the observed values according to density functional theory (DFT) method and analyzed.
