Measured line positions and strengths of methane between 5500 and 6180 cm^−1

Abstract

The positions and strengths of more than 2000 methane absorption lines stronger than 1.0 x 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 2nu(3) band strength of (12)CH(4) was determined to be 1.641 cm(-2) atm(-1); a Herman-Wallis-type correction was also determined to be (1 + 0.0298 m + 0.000536 M(2)).
