Abstract:
The article describes the results of high-precision ro-vibrational analysis of the ethylene molecule. Several studies strongly interacting states in the range of 800 - 1200 ρμ$^{-1}$ have been performed. These studies have enabled us to significantly improve the information on the ground vibrational state.
Keywords:The theory of vibrational-rotational interactions in molecules; intramolecular potential function; methods for determining the potential function method of the global fitting method of combination differences.
