✦ Synopsis

The effective operator approach has been applied to the calculation of line intensities of 12C16O2. Using the eigenfunctions of our reduced effective Hamiltonian (1992, J. Mol. Spectrosc. 156, 48-64) the experimental line intensities of cold and hot bands lying in the regions of 15, 10, and 5 μm have been fitted to parameters of the corresponding effective dipole moment matrix elements. The quality of fittings and the extrapolational properties of the fitted parameters are discussed. Formulas in terms of basic molecular properties for some of the parameters of the effective dipole moment matrix elements are derived. Values of these parameters calculated from the theoretical formulas using the force field and dipole moment expansions of Wattson and Rothman (1992, J. Quant. Spectrosc. Radiat. Transfer 48, 763-780) have been compared with corresponding fitted values. Copyright 1998 Academic Press. Copyright 1998Academic Press
