Electronic absorption/emission, 1H NMR spectroscopy and quantum mechanical calculations have been used to characterize the ground-state conformation of o-methoxy-and o-hexyloxy-benzamides in different solvents. Experimental evidence supports the assumption that a conformation having an intramolecular H-bond between one amide hydrogen and the o-alkoxy oxygen is significantly populated even in aqueous solutions.

Abstract
Electronic absorption/emission, 1H NMR spectroscopy and quantum mechanical calculations have been used to characterize the ground-state conformation of o-methoxy-and o-hexyloxy-benzamides in different solvents. Experimental evidence supports the assumption that a conformation having an intramolecular H-bond between one amide hydrogen and the o-alkoxy oxygen is significantly populated even in aqueous solutions.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
