Abstract

The positions and strengths of more than 2000 methane absorption lines stronger than 1.0 × 10−4 cm−2 atm−1 have been measured in the 5500–6180-cm−1 spectral region. The measurements were made using spectra recorded at room temperature (296 K) with a resolution of 0.01 cm−1. The spectra were obtained using the Fourier transform spectrometer at the McMath solar telescope at the Kitt Peak National Observatory. The 2ν3 band strength of 12CH4 to be 1.641 cm−2 atm−1; a Herman-Wallis-type correction was also was determined determined to be (1 + 0.0298 m + 0.000536 m2).
