Theoretical investigation of normal to strong hydrogen bonds

Abstract

We review our theoretical work done on a variety of different chemical systems, which show different H-bonding characteristics. The systems include water clusters, its interactions with polar molecules and pi-systems, organic nanotubes, enzymes, and ionophores/receptors. Special features of normal, short, short strong, and pi-type H-bonding interactions in these systems are discussed in terms of structures, interaction energies, and spectra.
