To determine high-precision values of rotational-vibrational levels of the ground state of the 13C12CH4 molecule, high-resolution spectra in the infrared range 600–1700 cm–1 and microwave transitions known from the literature are used. The rotational and centrifugal parameters of the ground vibrational state with root-mean- square deviation that is by about thousand times smaller than for the parameters known from the literature are determined based on the obtained information.
