The emission spectrum of a chemical element or chemical compound is the relative intensity of each frequency of electromagnetic radiation emitted by the element's atoms or the compound's moleculeswhen they are returned to a ground state. Each element's emission spectrum is unique. Therefore, spectroscopy can be used to the identify the elements in matter of unknown composition. Similarly, the emission spectra of molecules can be used in chemical analysis of substances.
