Abstract
In the present work, a combined experimental and computational study for the optimized molecular structural parameters, FT-IR spectra, thermo-chemical parameters, total dipole moment and HOMO-LUMO energy gap for 2-chloro-5-(2,5-dimethoxy-benzylidene)-1,3-diethyl-clihydro-pyrimidine-4,6(1H,5H)-dione have been investigated using B3LYP/6-311G basis set. Our calculated results have showed that the investigated compound possesses a dipole moment of 4.9 Debye and HOMO-LUMO energy gap of 3 eV which indicate high recommendations for photovoltaic devices fabrication.
