Optical Emission Spectroscopy
Optical emission from a plasma occurs primarily through the electron impact excitation of atoms or molecules to an excited state, followed by a relaxation to a lower energy state releasing a photon containing an energy equal to the difference between these two energy states. Analysis of the photon energy (wavelength of light) and spectral emission information of species can therefore be used to infer the composition of the species that produced it.
