WebOct 3, 2016 · Doppler broadening is due to the thermal motion of the emitting atoms or ions. For a Maxwellian velocity distribution, the line shape is Gaussian; the full width at half maximum intensity (FWHM) is, in Å, ΔλD1 / 2 = (7.16 × 10 − 7)λ(T / M)1 / 2. T is the temperature of the emitters in K, and M the atomic weight in atomic mass units (amu).
