MOLECULAR ORBITAL THEORY AND UV SPECTROSCOPY

Molecular orbital (MO) theory describes covalent bond formation as a combination of atomic orbitals to form molecular orbitals. MO’s represent regions of space in a molecule where electrons spend > 90% of their time, traveling in wave-like motion. In the H2 molecule 2 singly occupied 1s atomic orbitals combine to produce 2 molecular orbitals... ................
