We model the carbon monoxide ro-vibrational spectra of a cometary coma illuminated by incident solar radiation, including a full treatment of radiative transfer. Our model uses a plane parallel approximation divided into multiple layers or "slabs". For each slab we calculate fractional molecular population distributions for the relavant vibrational and rotational quantum states using statistical equlibrium. We then solve the radiative transfer equation for each ro-vibratioanl line using the just calculated population distributions, Einstein coefficients and number density to determine the optical depth and single scattering albedo for each line. The transfer equation is then solved using lambda iteration. The calculated source functions for each line are then used to recalculate the molecular population distribution. The process is iterated until converging on a consistent solution. We include the incident solar radiation, coherent scattering, absorption and emission in our radiative transfer calculation for each line frequency for all slabs of coma gas. This approach produces model spectra, including redistribution of flux between lines, for varying optical depths throughout the cometary coma.
