Notes on fluorescence spectroscopy
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 absorp… WebJan 5, 2024 · An absorption leads to a higher energy state, fluorescence leads to a lower energy state, and the shift in nuclear coordinates between the ground and excited state is indicative of a new equilibrium position for nuclear interaction potential.

A fluorometer is an instrument designed to measure the various parameters of fluorescence, including its intensity and wavelength distribution of the emission after excitation. Chemists use this to identify properties and the amount of specific molecules in a sample.
