The main advantage of fluorescence detection compared to absorption measurements is the greater sensitivity achievable because the fluorescence signal has a very low background. For molecules that can be resonant excitated, LIF provides selective excitation of the analyte to avoid interferences. LIF is useful to study the electronic structure of molecules and to make quantitative measurements of analyte concentrations. Analytical applications include monitoring gas-phase concentrations in the atmosphere, flames, and plasmas; and remote sensing using light detection and ranging (LIDAR))

In addition, variations on this basic technique include PLIF (planar laser-induced fluorescence) LIPF (laser-induced pre-dissociative fluorescence) and others). ... LIF is a process whereby molecules/atoms are excited to higher electronic energy states via laser absorption and subsequently fluoresce; the intensity of this fluorescence is, in general, a function of the species concentration (number density), and the gas temperature and pressure. Among other things, this fluorescence is linearly dependent on the absorber number density. By virtue of the fact that the energy states of molecules/atoms are quantized, the spectral absorption regions are discrete; however, for large molecules, the spacing of the discrete transitions may be sufficiently small (and the number of transitions sufficiently great) that discrete absorption regions are not observed (only absorption bands are observed). Typically, fluorescence occurs at wavelengths greater than or equal to the laser wavelength, and again for atoms and diatomic molecules especially, discrete fluorescence transitions may be observed)
