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. WebOct 19, 2024 · Spectroscopy is the measurement of the absorption and emission of light and other radiation by materials. It comprises of separating light (or, more correctly, electromagnetic radiation) into its constituent wavelengths (a spectrum), similar to how a prism divides light into a rainbow of colours. Spectroscopy was originally defined as the …
