Аннотация
Solvation state of pyridine-3-carboxamide (nicotinamide) was studied by means of different temperature nuclear magnetic resonance spectroscopy at different compositions of water–dimethyl sulfoxide solvent. The breaking of hydrogen bonds between heteronitrogen and water molecules takes place at XDMSO ~ 0.2–0.3 m.f. Changes in carboxamide substituent solvation consisting in the disappearance of water molecules occur at XDMSO ~ 0.4 m.f. The quantum chemical modeling of some nicotinamide solvates was performed along with NBO analysis and chemical shift calculations.
