Actual line shapes are determined principally by Doppler, collision and proximity broadening. For each system the half-width of the shape function varies with temperature, pressure (or concentration) and phase. A knowledge of shape function is needed for spectroscopic curve fitting and deconvolution . Se mer Spectral line shape describes the form of a feature, observed in spectroscopy, corresponding to an energy change in an atom, molecule or ion. This shape is also referred to as the spectral line profile. Ideal line shapes include Se mer Atomic spectra For atoms in the gas phase the principal effects are Doppler and pressure broadening. Lines are relatively sharp on the scale of measurement so that applications such as atomic absorption spectroscopy (AAS) … Se mer • Fano resonance • Holtsmark distribution • Zero-phonon line and phonon sideband Se mer An atomic transition is associated with a specific amount of energy, E. However, when this energy is measured by means of some … Se mer Lorentzian A Lorentzian line shape function can be represented as $${\displaystyle L={\frac {1}{1+x^{2}}},}$$ where L signifies a … Se mer Curve decomposition Some spectroscopic curves can be approximated by the sum of a set of component curves.

Nettet1. apr. 2005 · We theoretically show that the spectral density (the line shape) which is compatible with these results is a Voigt profile whose Lorentzian part or homogeneous component is linked to the white noise and the Gaussian part to the 1/f noise. We measure semiconductor laser line profiles and verify that they can be fit with Voigt functions.
