On the detection of higher order carbon sulfides (CSx; x = 4-6) in low temperature carbon disulfide ices

- Higher carbon sulfides CSx (x = 4-6) are detected in electron irradiated CS2 ices.
- The products are monitored via infrared spectroscopic detection at 12 K.
- Ab initio calculations are used to predict the structures and IR frequencies.
- Observed and calculated isotopic shifts are used to verify the assignments.
- The stabilities of the products are verified at higher temperatures.
