On the Use of a Gauss Filter in the Deconvolution of Lorentzian Spectral Lines

Not Accessible

Your library or personal account may give you access


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.
