A new digital computational method of spectral line shape analysis is reported. In the present method, the parameters of object functions are directly found to fit the experimental values on the basis of a nonlinear least squares method. The present method is available for curve fitting of experimental results if the functions are expressed in analytical form. As an example, the results of resolving the recorded Raman spectra into the component line shapes is presented. The agreement of the recorded Raman spectra with that composed of the resolved lines is excellent.
