摘要
An overview is given of the relationship between H-bond and pi-electron delocalization. Hydrogen atom is associated with electron delocalization in terms of location and its interactions with both neighboring atoms. The H-bond may be associated with cooperative interactions discussed in terms of the resonance-assisted H-bond, which lead to π-electron delocalization of distand bonds built of atoms bearing π electrons. The changes of these parameters are associated with the changes in charge distribution in the region of the H-bond. Phenomena are revealed in the AIM and aromacity parameters as well as C NMR chemical shifts.
