Laboratory Excitation of the Blue-Green Bands Observed in the Spectra of N-Type Stars.
Abstract
A complex band spectrum has been excited in a King furnace charged with silicon. The main features of the spectrum agree with those of the hitherto unidentified blue-green bands occurring in the spectra of some N-type stars. It is concluded from the complexity of the bands that the emitter is a polyatomic molecule. On the basis of a partial vibrational analysis and the experimental conditions for producing the bands, as well as the appearance in the spectra of cool carbon stars, the spectrum is tentatively ascribed to an Si-C-C molecule.
