Intrinsic bond orbitals (IBO) are localized molecular orbitals giving exact and non-empirical representations of wave functions. They are obtained by unitary transformation and form an orthogonal set of orbitals localized on a minimal number of atoms. IBOs present an intuitive and unbiased interpretation of chemical bonding with naturally arising Lewis structures.[1] For this reason IBOs have been successfully employed for the elucidation of molecular structures[1] and electron flow along the intrinsic reaction coordinate (IRC).[2]
IBOs have also found application as Wannier functions in the study of solids.[3]
