Every time a photon hits a molecule and is particularly absorbed, the molecule is promoted into a much more enthusiastic energetic condition. UV-seen light-weight has more than enough energy to promote electrons to a greater electronic condition, from the very best occupied molecular orbital (HOMO) to the lowest unoccupied molecular orbital (LUMO). The Strength distinction between the HOMO plus the LUMO is known as the band gap. Ordinarily, these orbitals are known as bonding and anti-bonding. The Power in the photon ought to exactly match the band gap for that photon to generally be absorbed. So, molecules with distinct chemical constructions have different Vitality band gaps and distinctive absorption spectra.
