emission spectrum

n.
The spectrum of bright lines, bands, or continuous radiation characteristic of and determined by a specific emitting substance subjected to a specific kind of excitation.

emission spectrum

n
(General Physics) the continuous spectrum or pattern of bright lines or bands seen when the electromagnetic radiation emitted by a substance is passed into a spectrometer. The spectrum is characteristic of the emitting substance and the type of excitation to which it is subjected. Compare absorption spectrum

e·mis·sion spectrum

The pattern of dark lines and colors made when electromagnetic energy, such as light, passes through a substance and excites its atoms. The excited atoms give off energy in the form of light. Because each type of atom gives off light having a unique range of colors, the emission spectrum can be used to determine the substance's chemical composition.
