[′bän·diŋ ′ȯr·bəd·əl]
(physical chemistry)
A molecular orbital formed by a bonding electron whose energy decreases as the nuclei are brought closer together, resulting in a net attraction and chemical bonding.

The electron in the excited state need not have the same set of quantum numbers as the electron with which it was paired in the bonding orbital in the ground state before absorption.
Far from the surface and in the absence of a field, the atomic orbitals of A and B hybridize into molecular orbitals which we take to be a low-lying bonding orbital and an empty antibonding orbital.
Scientific impact:(a): Site-specific 2D-x-ray spectroscopy will phase-sensitively test&promote theory and allow to understand fundamental processes: excitation, ionization, and few-electron dynamics in atoms and molecular bonding orbitals.
