text: Among its few known reactions, CS reacts with bromine to form the cyclic disulfide.
  CS polymerizes under applied pressure to give a black semi-conducting solid. A similar pressure-induced polymerization of CS also gives a black semiconducting polymer.
  In addition, reactions of CS can yield highly condensed sulfur-containing compounds, e.g. the reaction of CS with 2-aminopyridine.
  Using microwave spectroscopy, small CS clusters have been detected in interstellar medium. The rotational transitions of these molecular carbon sulfides matched with the corresponding molecules.
