To promote better modeling of brown dwarf stars and exosolar planets, some 10,000 line intensities of methane are being measured between 4800 and 9100 cm-1. Intensities are being retrieved line-by-line from laboratory spectra recorded at 0.01 and 0.02 cm-1 resolution using the McMath-Pierce Fourier transform spectrometer at the National Solar Observatory located at Kitt Peak. Empirical linelists of observed line positions and intensities for the 4800 to 5350 cm-1 and 7400 to 7800 cm-1 spectral intervals are being compiled to support an ongoing effort by others to obtain an ab initio calculation of the methane spectrum. Preliminary values are also being obtained for the 8200 to 8900 cm-1 region.
The research described in this paper was performed at the Jet Propulsion Laboratory, California Institute of Technology, under contract with The National Aeronautics and Space Administration through funding provided by the OSS Origins program. The operation of the FTS is supported in part by a grant from the Upper Atmospheres Research Program.
