[ə¦täm·ik flu̇¦res·əns spek′träs·kə·pē] (spectroscopy) A form of atomic spectroscopy in which the sample atoms are first excited by absorbing radiation from an external source containing the element to be detected, and the intensity of radiation emitted at characteristic wavelengths during transitions of these atoms back to the ground state is observed.
