Hydrogen bonds (HBs) are crucial intermolecular interactions with unique properties that significantly influence the behavior of various systems such as water, ices, hydrogels, proteins, and DNA molecules. Despite their importance, analyzing HBs in complex systems has been challenging due to their directional and electrostatic nature. In a recent study, researchers introduced a novel approach to understand HBs by conceptualizing them as an electric dipole moment interacting with an electric field induced by the acceptor group. This dipole-in-E-field model offers a more precise and universal way to quantify HB strength and directionality, enabling predictions about the properties of systems with complex HB networks. By using this model, the researchers were able to analyze HBs in nanoconfined water within a hydrogen-bonded heterostructure gypsum system. The study demonstrates how the new approach can provide insights into the electrostatic nature of HBs and the effects of external electric fields on these interactions. This research not only enhances our understanding of HBs but also offers a practical method to predict and analyze hydrogen bonding in various systems, paving the way for advancements in this field.
