Einstein coefficients

Emission lines and absorption lines compared to a continuous spectrum.

Schematic diagram of atomic spontaneous emission

Schematic diagram of atomic stimulated emission

Einstein coefficients are mathematical quantities which are a measure of the probability of absorption or emission of light by an atom or molecule. The Einstein A coefficient is related to the rate of spontaneous emission of light and the Einstein B coefficients are related to the absorption and stimulated emission of light.
