We re-processed spectroscopic echelle data on 1999 S4 (LINIER), a catastrophically disintegrated comet, and 2001 Q4 (NEAT) obtained at not quite favorable circumstances. Photometric conditions at the observations were good but measurements of the spectra for the first one were performed at a large zenith distance and the second - with a relatively low spectral resolution. Nevertheless, we succeeded in detection and identification of fluorescent emission lines of 9 polycyclic aromatic hydrocarbons and simpler molecules in the spectra of both comets. Our results are in accordance with those of other authors and substantiate present notions about origin of the comets.

Keywords: spectroscopy of comets; molecular emission lines; organic compounds
