    Abstract

    The electronic spectrum of a member of a so-far-unstudied class of carbon chain radicals was observed:a nonlinear and noncyclic species. The spectrum was observed more or less accidentally around 604 nm when scanning for coincidences with diffuse interstellar band features in a hydrocarbon plasma. The observed spectrum has a clear rotational and K-type structure. Simulation of the spectrum allowed an accurate determination of the molecular constants of the carrier.
