ResumoA method for fitting a Gaussian spectrum without iterative procedure is presented. The method utilizes a linearization technique of the Gaussian function and the standard linear least-squares fitting. Experimental and pseudo-experimental peaks have been used to test this method and a comparison with the conventional non-linear least-squares method has been made. The present method has the advantages of not requiring the initial estimates of Gaussian parameters, and not requiring large computer memory.
