Low-energy electron interactions with dimethyl disulphide

Electron attachment experiments have been performed with dimethyl disulphide, C2H6S2, in the gas phase by means of a crossed electron-molecular beam experiment. Ion yields for 8 anions have been measured in the energy range from ∼0 to 15 eV. Many of the dissociative electron attachment products observed at low energy arise from surprisingly complex reactions associated with multiple bond cleavages as well as structural and electronic rearrangement. Quantum chemical calculations on the electronic properties of C2H6S2 have been performed in order to complement the experimental investigations.
