Doppler broadening comparison table

Subject	has effect	is a kind of	has cause	has definition
line broadening		radiation modification		Increase in the range of wavelengths in which some characteristic emission or absorption occurs.
Doppler broadening	small displacements of radiation absorbed or emitted by atoms toward longer and shorter wavelengths result in broadening of the lines	line broadening	thermal, turbulent, or mass motions of atoms along the line of sight	Line broadening caused by the thermal, turbulent, or mass motions of atoms along the line of sight.
