Abstract

The analytical form of a Fabry–Perot interferogram of a periodic spectrum has been obtained, which is a function of a single adjustable parameter. This parameter may either be determined directly from experimental data or, as in this paper, from a computer-simulation experiment. This method is applied to the analysis of interferograms of rotational Raman spectra. The interferogram profile is a sensitive function of the parameters that determine the intensity and width of the individiual rotational Raman lines. The intrinsic multiplex advantage of this technique in the study of periodic spectra is also discussed.
