Abstract
The experimental FT-IR spectral analysis of 9-chloroanthracene has worked out by using density functional theory (DFT). The optimized molecular structure and minimum energy of 9-chloroanthracene has analyzed using DFT/B3LYP functional employing 6-311++G(d,p) basis set. The vibrational frequencies along with IR intensities were computed, scaling was used for a better fit between the experimental and computed frequencies, they agreed with rms error 8.48 cm-1 for 9-chloroanthracene. The NLO behaviour of the molecule is investigated from first-order hyperpolarizability. The HOMO and LUMO energies are evaluated to demonstrate the chemical stability, reactivity of molecule. The MESP over the molecules were plotted to evaluate electron density regions and thermodynamic parameters are calculated. Hyper conjugative interactions and charge delocalization of the molecule study from NBO analysis and Fukui functions are evaluated for 9-chloroanthracene. The molecular docking studies were performed against anticancer protein targets Tyrosinase and HER2.
