It is well known that when the FIRO deconvolution method is used, maximum resolution enhancement results from self-deconvolution, e.g., when a Lorentz filter is used to deconvolute a mostly Lorentzian line shape [Applied Spectroscopy 35, 271 (1981)]. Unfortunately, self-deconvolution can also distort the line shape and introduce side lobes. In this paper it is shown that a Gauss filter can be used to deconvolute a Lorentzian line or lines and produce some resolution enhancement without significantly distorting the line shape or introducing other undesirable features.
