Scientific paper

A complex organic solid produced from cosmically abundant molecules explains many properties of the interstellar grains and gas. The product, a brown, sometimes sticky residue that is resistant to conventional analytic chemistry, has been named tholins and is discussed as a major constituent of the interstellar medium. Sequential and nonsequential pyrolysis followed by gas chromatography/mass spectroscopy were used to determine something of the composition of this material. The production and properties of tholins produced by spark discharges and by ultraviolet light are examined.
