Abstract
In the present study, CT interaction between the norfloxacin antibiotic drug (Nor) as a donor and picric acid (PA) as acceptor was investigated experimentally and theoretically using computational software Gaussian 09. Optimized molecular structural parameters such as HOMO-LUMO, bonding
features include 1H NMR, UV-Vis., vibrational frequencies have been examined. The electronic excitation properties of UV-Vis. data using density functional theory giving assignment of the major spectral features for the Nor-PA CT complex.
