Abstract
We have applied the tools of laser induced fluorescence and dispersed fluorescence to the products of a benzene discharge in a free jet with a view to identifying new hydrocarbon radicals. We have observed several new band systems in the visible and UV regions, including a putative origin at 4759\AA (air) which fluoresces to a ground state exhibiting vibrational modes at 120\,cm$^{-1}$, 821\,cm$^{-1}$, 988\,cm$^{-1}$ and 1160\,cm$^{-1}$. This species is of particular interest due to its proximity to the centre of the (very) diffuse interstellar band at 4761.7\AA\ (FWHM 25\AA).
