     summary: The reason in this case remains unclear, not withstanding a basic explanation of reaction rate of organic compound, which is completely different from the ionic compound. The explanation of reaction rate is necessarily connected to the TD- function, because chemical activation of any compound depends on internal potential energy.

     summary: J. Chem., 23(49), 2022, 19-26 For fully characterizing hydrogen bond interactions, we have utilized many other quantum chemical calculations in addition to BEs, such as the hydrogen bond length, the NPA charges of the atoms at the ends of the hydrogen bonds, and ESP. The bonding mechanism of hydrogen bonds is different from chemical bonds in that hydrogen bonds are a special type of the intermolecular force, dipole-dipole.
