WebDec 7, 2015 · Fluorescence is the process by which a molecule absorbs a photon of light exciting an electron to a higher energy state. This electron often relaxes down to the lowest vibrational level of the excited state and … Fluorescence spectroscopy (also known as fluorimetry or spectrofluorometry) is a type of electromagnetic spectroscopy that analyzes fluorescence from a sample. It involves using a beam of light, usually ultraviolet light, that excites the electrons in molecules of certain compounds and causes them to emit light; typically, but not necessarily, visible light. A complementary technique is absor…
