In order to better understand the innermost regions of cometary comae, such as those observed with high spatial resolution in the Deep Impact and EPOXI missions, we have built a radiative transfer model for optically thick molecular emission spectra. We use Coupled Escape Probability, a new accurate method of radiative transfer, which we have improved to be used in an asymmetric spherical situation. Our model can also be of use in other applications and/or geometries, such as, for example, in protoplanetary disks. Four species/molecules have been modeled thus far: CO, CO2, H2O and SiO. The first three are particularly relevant for Deep Impact/EPOXI observations of Tempel 1 and Hartley 2, as well as other cometary spectra. SiO is for use in protoplanetary disk studies.
