16O13C18O:: high-resolution absorption spectrum between 4000 and 9500 cm-1 and global fitting of vibration-rotational line positions

The absorption spectrum of a 3 C enriched carbon dioxide sample has been recorded with a Fourier-transform spectrometer in the spectral range 4000-9500 cm(-1). In addition to six bands observed from the spectrum of the atmosphere of Venus in this region, eight new 16011 00 bands were measured. The new observations together with the data collected from the literature have been used to fit parameters of an effective Hamiltonian for the (OCO)-O-16-C-13-O-18. More than 4000 line positions in 38 bands have been used to derive 48 parameters of effective Hamiltonian. The RMS (root-mean-square of residuals) of the fit is 0.00106 cm(-1). (C) 2003 Elsevier Inc.
