A small computer, forming part of an NMR Fourier transform spectroscopy installation, has been programmed to analyze spectra consisting of overlapping lines such as are obtained from quadrupolar nuclei or in Raman spectroscopy. A rough visual fit to the data, which is displayed on an oscilloscope, is obtained by manual insertion of parameters and the fit is refined automatically using a sequential direct search method, thus eliminating the tedious stage of manual refinement. The equipment has proved easy and convenient to use.
