The energetics of S 2 +·ion formation in electron dissociative ionization of linear CS 2 are investigated experimentally with a crossed‐beam apparatus. Ab initio self‐consistent‐field molecular orbital (SCF MO) calculations of potential energy curves for low‐lying electronic states of this ion have been made in order to explain how stable S 2 +·ions are formed, initially at the very large internuclear separation of 3.2 Å.
