Visible absorptions of potential diffuse ISM hydrocarbons: C9H9 and C9H5 radicals.

STEGLICH M., MAITY S. and MAIER J.P.

Abstract (from CDS):

The laboratory detection of previously unobserved resonance-stabilized C9H5 and C9H9 radicals in the supersonic expansion of a hydrocarbon discharge source is reported. The radicals are tentatively assigned as acetylenic-substituted cyclopentadienyl C9H5 and vinyl-substituted benzyl C9H9 species. They are found to feature visible absorption bands that coincide with a few very weak diffuse interstellar bands toward HD183143 and HD204827.
