Scientific paper

We have calculated synthetic spectra of perpendicular and parallel rovibronic bands of cumulene carbene molecules of the form CnH2. The perpendicular bands are consistent with a regularly spaced group of diffuse interstellar bands (DIBs) near 6850Å. Parallel bands calculated for these molecular structures are consistent with the intrinsic profile of the associated 6614-Å DIB. Both types of bands are expected for an electronic transition that these species should have at those energies. We could not determine if the molecule was charged or if an atom other than carbon terminated the chain-end. Constraints due to molecular geometry and temperature place the chain length at 7-15 carbons to fit the 6850-Å group and 9-13 carbons to fit the 6614-Å DIB.
