A 'non-classical' information theory of spectral line shape
J G Powles and B Carazza
Show affiliationsInformation theory is used to obtain the most probable spectral line shape given only a knowledge of a finite number of moments of the line. The analysis of Powles and Carazza is extended to a consideration of non-classical information theory. This gives the possibility of a Lorentzian line shape which was not previously available. It is shown, in particular, that the common observation of a line shape narrowing from Gaussian to Lorentzian is simply explained and can be related to a change in physical parameters. The method is applied to problems in magnetic resonance but is of wide validity.
