Abstract
COMETARY emission spectra exhibit features of such diatomic radicals as CN, C2, OH, CO+, N+2 (ref. 1) which almost certainly arise from photon or corpuscular irradiation of polyatomic species in the comet head2. The emission spectra are almost certainly excited by resonance fluorescent excitation by solar photons3. Little laboratory work has been done on the kinetics of excitation processes of cometary spectra. In this report we record some recent work on the fluorescent excitation of CN in a static system.
