Interrelation between H-bond and pi-electron delocalization

Article Abstract:

H-bond reveals a situation in which a more or less ionized hydrogen atom is immersed in electron clouds of the two closest negatively charged atoms belonging to different or the same molecule. If the H-bond ring is fused to the aromatic, system, it may affect dramatically pi-electron delocalization in the aromatic part of the system.
