Analysis of the Ground Vibrational State of the Ethylene-1-13C (13C12CH4) Molecule

Аннотация

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.
