Significant Intensity

Depolarized Raman spectra of compressed hydrogen gas have been computed rigorously previously for 36 K and 50 K (Gustafsson et al. (2009)). The far wings of the rotational lines show asymmetry that goes beyond that expected from the theory for intracollisional interference and Fano line shapes. Here we analyze the (0) line for pure hydrogen at 36 K in detail. The added asymmetry stems partly from a shape resonance which adds significant intensity to the higher frequency side of the line profile. The influence of the threshold energy for the rotational transition accounts for the remainder.

Experimental Values

A new digital computational method of spectral line shape analysis is reported. In the present method, the parameters of object functions are directly found to fit the experimental values on the basis of a nonlinear least squares method. The present method is available for curve fitting of experimental results if the functions are expressed in analytical form. As an example, the results of resolving the recorded Raman spectra into the component line shapes is presented. The agreement of the recorded Raman spectra with that composed of the resolved lines is excellent.
