TL;DR: In this paper, an effective dipole-moment operator was applied to the calculation of both line positions and line intensities of the 13C16O2 molecule and the eigenfunctions of this effective Hamiltonian have then been used in fittings of parameters of an effective Dipole-Moment operator.

TL;DR: In this article, the effective operator approach is applied for the global fitting of the vibrational-rotational line positions of acetylene molecule, and the standard deviation of the fit is 0.0009 cm.
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$.© (2000) COPYRIGHT SPIE--The International Society for Optical Engineering.
