The HOMO-LUMO gap is the energy difference between the Highest Occupied Molecular Orbital (HOMO) and the Lowest Unoccupied Molecular Orbital (LUMO) in a molecule, which is crucial for determining its electronic properties and chemical reactivity. A smaller gap often correlates with higher reactivity and lower stability, influencing phenomena such as color, conductivity, and the efficiency of photovoltaic and light-emitting devices.

Electronic properties refer to the behavior and characteristics of electrons in materials, which determine a material's electrical conductivity, band structure, and other related phenomena. Understanding these properties is crucial for the development of electronic devices and materials science innovations.
