A conformational and electronic study on N-acetyl-l-isoleucine-Nmethylamide was carried out. All side-chain as well as backbone conformations were explored for this compound. Multidimensional conformational analysis predicts 81 structures in the case of N-acetyl-l-isoleucine-N-methylamide, 53 relaxed structures were determined at the DFT (B3LYP/6-31G(d)) level of theory. An exhaustive electronic study employing the atoms-in-molecules (AIM) method was carried out. In addition, the effects of three solvents (water, acetonitrile, and chloroform) were included in the calculations using the isodensity polarizable continuum model (IPCM) method. were determined at the DFT (B3LYP/6-31G(d)) level of theory.
