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

Autor: Poul Erik Hansen

Publikováno v: Molecules, Vol 20, Iss 2, Pp 2405-2424 (2015)

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 impo

Theoretical Study of Heteroatom Resonance-Assisted Hydrogen Bond: Effect of Substituent on π-delocalization

Autor: Ali Heydar Pakiari, Maryam Farrokhnia

Publikováno v: Iranian Journal of Chemistry & Chemical Engineering, Vol 29, Iss 4, Pp 197-210 (2010)

The concept of Resonance Assisted Hydrogen Bond (RAHB), which usually occurs in b diketons, has a remarkable role in chemistry. These molecules, which contain heteroatom particularly O and N, are species with biological interest in protein folding an

The fact that intramolecular resonance-assisted hydrogen bonds (RAHBs) are stronger than conventional ones is attributed to the partial delocalization of the pi-electrons within the hydrogen bond (HB) motif, the so-called quasi-ring. If an aromatic r
