✦ Synopsis

Sulfur ions in the *D; excited state are observed to charge exchange with OCS molecules. These excited ions are created usmg resonantly enhanced multiphoton iomzation of sulfur atoms generated from photodissociation of parent OCS. Evidence for ionic state-selection is documented with photoelectron spectroscopy. Ground state sulfur ions produced via two-photon autoionization through the 3s23p35p 'P, state at 87624 cm-' do not exhibit charge exchange reactions under identical conditions.
