Spectroscopic, X-ray Diffraction and Density Functional Theory Study of Intra- and Intermolecular Hydrogen Bonds in Ortho-(4-tolylsulfonamido)benzamides

Autor: Malose J. Mphahlele, Eugene E. Onwu, Marole M. Maluleka

Publikováno v: Molecules, Vol 26, Iss 4, p 926 (2021)

The conformations of the title compounds were determined in solution (NMR and UV-Vis spectroscopy) and in the solid state (FT-IR and XRD), complemented with density functional theory (DFT) in the gas phase. The nonequivalence of the amide protons of
