sion and Absorption Spectra The spectrum of radiation emitted by a substance that has absorbed energy is called an emission spectrum Atoms molecules or ions that have absorbed radiation are said to be excited To produce an emission spectrum energy is supplied to a sample by heating it or irradiating it and the wavelength or frequency of the radiation emitted as the sample gives up the absorbed energy is recorded An absorption spectrum is like the photographic negative of an emission spectrum A continuum of radiation is passed through a sample which absorbs radiation of certain wavelengths The missing wavelength which corresponds to the radiation absorbed by the matter leave dark spaces in the l
