Wdowiak, T. J. Abstract A method of synthesis via plasma discharge and rare gas cryogenic matrix isolation has produced large carbon-containing molecules from a 0.5% methane in argon mixture, giving rise to a reproducible pattern of features corresponding to diffuse interstellar bands (DIBs), including the strongest and widest 4430 (4428) A diffuse interstellar band, the second strongest and wide 6283 (6284) A DIB along with its narrower and shorter wavelength companion, the 6269 A DIB, and the 5778-5780 A DIBs. Because of matrix effects wavelengths are shifted slightly from their observed interstellar wavelengths. Importantly, the laboratory-produced spectral features are stable under irradiation of ultraviolet light produced by a mercury vapor lamp.
