line broadening

The production of broadened spectral lines by various effects. The natural width of a spectral line is determined by quantum mechanical uncertainty. Other factors can, however, produce extra line width, including rapid rotation of a celestial body, Doppler broadening, pressure broadening, and the Zeeman effect. Considerations of the line profile can give information about the physical conditions of celestial objects.

line broadening

[′līn ‚brȯd·ən·iŋ] (spectroscopy) An increase in the range of wavelengths over which the characteristic absorption or emission of a spectral line takes place, due to a number of causes such as collision broadening and Doppler broadening.
