In recent news, China's National Centre for Nanoscience and Technology has adjusted AFM (Atomic Force Microscopy) performed by chemists at UC Berkeley trying to see covalent bonds in order to see Hydrogen Bonds. This kind of technology advancement will help scientists/chemists to better understand the nature of the Hydrogen Bond. It is still a debate among scientists if Hydrogen Bonds actually 'bond' or if they have an electrostatic relationship, but perhaps with more time scientists will be better able to answer the relationship of Hydrogen Bonds.
