Fluorescence is the absorption and emission of light of two different frequencies. Typically, a lower wavelength of incident light is absorbed from one direction, and a higher wavelength of light is emitted in all directions.
Fluorescent molecules absorb light at a certain wavelength and emit at another. With a known incident light wavelength, samples can be identified by their fluorescent emission spectra. Because fluorescence occurs on a molecular scale, it is the only spectroscopic technique capable of identifying single molecules.
