: The theory posits that H-bond strength is maximized when the proton affinity (PA) or pKa of the donor and acceptor are matched, creating a "low-barrier" for the proton. Functional Importance

: Strong bonds where π-conjugation enhances the interaction. The Nature of the Hydrogen Bond: Outline of a C...

The review outlines how these specific types of hydrogen bonds drive critical chemical and biological processes: : The theory posits that H-bond strength is

: Extremely strong bonds formed when the donor and acceptor are charged. The Nature of the Hydrogen Bond: Outline of a C...

: While weak H-bonds are primarily electrostatic (dipole-dipole), strong H-bonds exhibit orbital overlap and partial covalent character.

The authors move away from a purely electrostatic view to a "twofold nature" that includes significant covalent contributions, especially in stronger bonds.

: A core feature of the book is the classification of H-bonds into six categories based on their strength and mechanism, including:
