Abstract: | Theoretical and experimental investigation of the formation of S 2 - from CS2 by electron impact has been carried out. Molecular orbital calculations show that some of the low lying states of CS 2 - have lower potential energy in the bent geometries suggesting a transformation in the geometric structure of the precursor molecular ion, leading to the formation of S 2 - . In contrast to the formation of S 2 - and S 2 - , the kinetic energy associated with S 2 - is small and disproportionate to the increase in electron energy, indicating the formation of S 2 - in vibrationally excited states due to the mechanism of its formation. |
