C–H⋯O hydrogen bonds and H⋯H bondinginteractions. These interactions have also been described and studied energetically using DFT calculations. The nature and strength of these intermolecular contacts have been rationalized by using several computational tools including molecular electrostatic potential (MEP) surfaces, natural bondorbital analysis (NBO), Bader's theory of atoms in molecules (QTAIM)
