Sumario:A conformational and electronic study on N-acetyl-L-isoleucine-N- methylamide 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.
