Sulphur solid- and gas-state chemical network derived from laboratory experiments, observational study of Cyg X-N12 and N30 (i.e., S-species observed in the cold- and warm-gas chemistries), and previous theoretical studies from Vidal et al. (2019, 2017), Vidal & Wakelam (2018), Laas & Caselli (2019), Vastel et al. (2018) and Deeyamulla & Husain (2006). The products found in the laboratory are highlighted in the blue boxes, and the species from the observation of cold gas of Cyg X-N12 are shown inside the dotted green boxes. The species detected toward Cyg X-N12 and N30 in the warm gas are shown inside the orange boxes. The straight lines represent the reactions with an additional reactant, shown by the plus. The dotted line represents the reaction found from the laboratory experiments. The gas-phase reactions are shown by black arrows, and the red arrows indicate the solid-state chemistry.
