Labile Protons and J-Coupling
Have you ever questioned why hydroxyl groups/alcohol signals appear as singlet in the 1H NMR spectrum? Shouldn’t they also couple with neighboring hydrogen atoms and show the corresponding splitting pattern? Yes…no…why? Don’t worry! We’ll get to the bottom of it and discuss how exchange rates, concentrations, and the presence of water affect the NMR spectra of ethanol in CDCl3. Benchtop NMR solves so many questions – feel free to reach out to us to make sure yours can answered too.
