The high resolution absorption spectra of 13CH4 were recorded at 81 K by differential absorption spectroscopy using a cryogenic cell and a series of Distributed Feed Back (DFB) diode lasers and at room temperature by Fourier transform spectroscopy. The investigated spectral region corresponds to the 13CH4 tetradecad containing 2nu3 near 5988 cm-1. Empirical linelists were constructed for 1629 transitions at 81 K (5852-6124 cm-1) and for 3488 features at room temperature (5850 - 6150 cm-1); the smallest observed intensity was 3×10-26 cm/molecule at 81 K. The lower state energy values were derived for 1208 13CH4 transitions using line intensities at 81 K and 296 K. Over 400 additional features were seen only at 81 K. The quality of the resulting empirical low energy values is demonstrated by the excellent agreement with the already-assigned transitions and the clear propensity of the empirical low J values to be close to integers. The two line lists at 81 K and at 296 K provided as Supplementary Material will enable future theoretical analyses of the upper 13CH4 tetradecad.
