WebSep 11, 2024 · 10.5: Emission Spectroscopy. An analyte in an excited state possesses an energy, E 2, that is greater than its energy when it is in a lower energy state, E 1. When the analyte returns to its lower energy state, the excess energy, Δ E = E 2 − E 1, is released as a photon, a process called emission. 10.6: Photoluminescent Spectroscopy.
