Comparison of the soluble products from radiolysis and photolysis of CS2

Soluble products from the radiolysis of CS2 with gamma variable rays from C o-60, include elemental sulfur and CmSn compounds. These compounds were ess entially the same as those that had already been reported for the UV photol ysis of CS2. The amount of sulfur formed was proportional to the irradiatio n dose. The radiolysis also formed a dark colored, insoluble polymer in amo unts proportional to the irradiation dose. The soluble CmSn molecules found in this work were most likely due to 'aborted polymerization'. Radiolysis and photolysis of CS2 may contribute important C-S compounds for the cosmoc hemistry of circumstellar and interstellar media as well as of comets and a tmospheres of the giant planets.
