The overlap of two 1s atomic orbitals in hydrogen, as shown in the diagram below, results in the formation of two molecular orbitals: One bonding (σ1s) orbital and one antibonding (σ*1s) orbital. Absorption of a high-energy photon can excite an electron from the bonding molecular orbital to the antibonding molecular orbital. Assuming that this transition is a HOMO-LUMO transition, identify the LUMO in hydrogen.
