The pseudo-voigt profile is a simple mathematical approximation to the Voigt profile commonly used in spectroscopy. While the Voigt profile function is an accurate depiction of spectral lines that result from a combination of gaussian and lorentzian line broadening, it is often computationally inconvenient due to the time-consuming convolution operation it entails. The pseudo-voigt profile, on the other hand, is just a linear combination of a Gaussian and a Lorentzian profile, and is thus extremely efficient to calculate. It has also been shown to approximate a true Voigt profile to a high degree of accuracy, and is therefore very convenient for fast computation.
