[ 1 ] - Electronic Structure, Biological Activity, Natural Bonding Orbital (NBO) and Non-Linear Optical Properties (NLO) of Poly-Functions Thiazolo [3,2-a]Pyridine Derivatives. DFT Approach
The optimized structures of studied compounds 23-28 are non planner with the two phenyl at C3 and C9 are out of the molecular plane of thiazolo[3,2-a]pyridine as indicated from a dihedral angles of 710 and 1160 respectively, using DFT-B3LYP method with 6-311G(d,p) as basis set. The natural bonding orbital (NBO) analysis of the parent molecule 23 have been analyzed in terms of the hybridization ...
[ 2 ] - TD-DFT Calculations, Electronic Structure, Biological Activity, NBO, NLO Analysis and Electronic Absorption Spectra of Some 3-Formylchromone Derivatives
The electronic structure and spectra of 3-formylchromone and some of its derivatives are investigated using TD-DFT/B3LYB/6-311G (d, p) level of theory. The results of calculations show that all the studied compounds 1–6 are planar, as indicated from the dihedral angles. The electronic absorption spectra of the studied compounds are recorded in the UV-Vis region, in both ethanol (as polar solven...
