= Low-barrier hydrogen bond
{wiki=Low-barrier_hydrogen_bond}
A low-barrier hydrogen bond (LBHB) is a type of hydrogen bond that has a shorter distance and a lower energy barrier compared to typical hydrogen bonds. In a typical hydrogen bond, the interaction between a hydrogen atom and an electronegative atom (like oxygen or nitrogen) results in a relatively stable bond, but the energy barrier for forming or breaking such bonds is usually higher. In contrast, LBHBs exhibit characteristics that allow them to form more easily and break more readily.
