Theoretical and experimental studies are performed on the new organic–inorganic hybrid molecule N‐(2,6‐dimethylphenyl)‐1‐piperazineacetamide. The vibrational spectra of the molecule are characterized using FT‐IR and FT‐Raman in the range 4000–600 cm−1 and 4000–100 cm−1, respectively. Density functional theory with B3LYP/3‐21G and B3LYP/cc‐pVDZ basis sets is used to calculate energy, geometrical structure, and vibrational modes of stretching, bending, and torsion. The VEDA software Autodock Vina revealed a good binding is employed to calculate the detailed vibrational assignments. The theoretical and experimental vibrational data are compared to support the present study. Density functional theory is used to calculate thermodynamic parameters (heat capacity, entropy, and enthalpy) and nonlinear optical properties. The software Gaussian09W and Gaussview 6.0 are used for theoretical calculations. Molecular docking studies are carried out to investigate the effect of the titled molecule against various proteins such as SARS‐CoV‐2 that affect the immune system in humans. Chemical shifts are identified using carbon and proton NMR. Non‐covalent interactions are studied using a reduced density gradient. The chemical reactivity and selectivity for a local reactivity site are analyzed with the help of Fukui functions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
