Abstract: Computations of vibration-rotation lines of the $\nu_{4}$ band of $^{12}CH_{4}$ at $1300 cm^{-1}$ have been extended to sixth order in perturbation theory. We have fit, by a least squares technique, a $0.04 cm^{-1}$ resolution laboratory spectrum obtained by Reisfeld $et al.^{1}$ at Los Alamos. We have assigned quantum numbers for approximately 250 lines in the $1200-1400 cm^{-1}$ region. The fourth order rotational constants of Husson and $Poussigue,^{2}$ derived from a lower resolution $spectrum,^{3}$ were used as starting values for the parameter search. We have calculated an improved fourth order fit to the spectrum and have also obtained parameters for a sixth order fit. The line strengths adopted here are consistent with the recent work of Fox $et al.^{4}$ Two examples of the application of this worm are given. First, a recent laser diode measurement in the $1200-1215 cm^{-1}$ region is compared to the theoretical spectrum. Second, the work is used to interpret spectra of Jupiter’s atmosphere obtained earlier this year with the infrared spectrometer on the Voyager spacecraft.
