Unified analytical approximation of Gaussian and Voigtian lineshapes
Description
Analytical approximation of the Voigt function has been derived. The Voigtian lineshape is reproduced without numerical integration or recourse to special functions. The formula derived contains also the Gaussian lineshape as a limiting case, thus allowing for pattern recognition if the appropriate lineshape is not a priori known. (author)
