Cooperative and Anticooperative Energy Effects in Systems with Classical Hydrogen Bonds

Cooperative and Anticooperative Energy Effects in Systems with Classical Hydrogen Bonds 

In contrast to those noted above, theoretical investigations of branched complexes in which two or more hydrogen bonds are formed by one proton-acceptor group, as in Structure 2.4, predict an inverse effect. In this case, mutual polarization weakens the hydrogen bonds, leading to anticooperative effects. The various factors governing the influence of the first hydrogen bond on the formation of
