Doppler broadening

(thermal broadening, thermal Doppler broadening)
(broadening of spectral lines due to velocities of the photon sources)

Doppler broadening (aka thermal broadening or thermal Doppler broadening) spectral line width due to the motion of the particles emitting the photons, e.g., thermal motion. By studying the shape of the line, inferences can be made about the source of the radiation.
