Abstract
This study aims to provide a comprehensive understanding of hydrogen bonds, which are the most significant directional molecular interactions in various chemical systems, ranging from inorganic to biological. The research examines the importance of hydrogen bonds in influencing molecular conformation, assembly, and function, as well as the evolution of related research, which saw a decline in the 1980s but rapidly resumed growth since the 1990s. The methodology employed in this study includes a theoretical and experimental review of various types of hydrogen bonds commonly found in condensed phases, as well as an analysis of interaction energy and covalent contributions in short, strong hydrogen bonds (SSHB). Additionally, the study adopts wave function analysis and the Quantum Theory of Atoms in Molecules (QTAIM) to evaluate hydrogen bond strength. The results indicate that hydrogen bonds exhibit diverse characteristics and are essential in various scientific disciplines, including supramolecular chemistry, biology, and inorganic chemistry. Hydrogen bonds play a critical role in stabilizing protein structures, proton transfer, and molecular self-assembly, and have significant implications in specific chemical reactions, such as the oxidative addition of bonds in complex molecules.
