Isotope Effects on Chemical Shifts in the Study of Intramolecular Hydrogen Bonds

Isotope Effects on Chemical Shifts in the Study of Intramolecular Hydrogen Bonds

The paper deals with the use of isotope effects on chemical shifts in characterizing intramolecular hydrogen bonds. Both so-called resonance-assisted (RAHB) and non-RAHB systems are treated. The importance of RAHB will be discussed. Another very important issue is the borderline between “static” and...
