Abstract
Analytical approximation of the Voigt function has been derived. The Voigti an lineshape is reproduced without numerical integration or recourse to spe cial 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. (C) 1999 Elsevier Science B.V.
