Abstract / Description of output

This paper evaluates two commonly accepted Raman lineshape models typically
used to fit CARS theory to data; the Modified Exponential Gap (MEG)
and the Energy Corrected Sudden (ECS) models. The adjustable parameters
in each model have been fit to published experimental linewidths, and
comparisons are made to the various publications that have already provided
similar adjustable constants. The approaches presented in the literature are
discussed as are differences with the findings presented here.
