Abstract

The effective operator approach is applied for the global fitting of the vibrational-rotational line positions of acetylene molecule. About 4470 line positions of the transitions involving vibrational-rotational energy levels up to 4200 cm^-1 have been used to determine 130 parameters of the effective Hamiltonian. The standard deviation of the fit is 0.0009 cm(superscript -1$.
