Title: INTERACTIVE ROTATIONAL ANALYSES OF DIATOMIC MOLECULAR SPECTRA
Creators: Abrams, M. C.; Davis, S. P.; Pecyner, R.
Issue Date: 1989
Abstract: The advent of interactive graphics on computers has permitted the development of interactive programs for the rotational analysis of the spectrum of diatomic molecules. The program ANALYSIS was developed specifically for the analysis of the spectra of medium to heavy diatomic molecules and attempts to duplicate the process an experienced spectroscopist uses to decompose a spectrum into bands and branches. Initially lines are identified and trial rotational parameters are computed, extrapolated line positions are suggested and accurate rotational parameters can be determined, even in cases where there are many missing lines or the heads are unresolved. The advantage of an interactive graphics program, as illustrated in figure 1, is that multiple branches can be displayed and fitted simultaneously and the results displayed in terms of the spectrum on the screen. Fitted lines are indicated by enhancing the linewidth of the display, and the dots below the spectrum indicate the positions of the fitted and extrapolated lines.
