Abstract

Using the effective Hamiltonian suggested in (V.I. Perevalov, E.I. Lobodenko, and J.-L. Teffo, "Reduced effective Hamiltonian for global fitting of C₂H₂ rovibrational lines", Proceedings of Twelfth Symposium and School on High-Resolutions Molecular Spectroscopy. SPIE. 3090, 143-149, 1997) the global fitting of the vibration-rotation line positions of acetylene molecule in the spectral range 0 - 9700 cm^-1has been performed. The effective Hamiltonian is based on the assumption of the cluster structure of vibrational energy levels. A set of 147 effective Hamiltonian parameters, which consists of 90 diagonal and 57 resonance parameters, has been fitted to 7291 line positions of 109 bands, collected from 10 different experimental sources. The RMS deviation of 0.0045 cm^-1has been achieved.
