Abstract
Unusual effects of intramolecular hydrogen bonds and dipole interactions are investigated using FTIR, NMR and X-Ray crystallography analyses of some imines. These phenomena affect both FTIR absorptions and chemical shifts.
Keywords: Intramolecular hydrogen bonds, dipole interactions, FTIR, 1H NMR
