Definitions for "Molecular Orbital"
The wavefunction which defines the properties (location etc) of an electron in a molecule. We speak of an electron that obeys such a wavefunction as occupying the relevant orbital.
Compare with atomic orbital and orbital. wavefunction that describes the behavior of an electron in a molecule. Molecular orbitals are usually spread across many atoms in the molecule, and they are often described as a combination of atomic orbitals on those atoms.
a region of space within the molecule where there is a high probability of finding a particular pair of electrons
