Nuclear motion in carbonyl sulfide induced by resonant core electron excitation

• The angular anisotropy for selected dissociation channels is measured at resonantly excited states of and symmetries at the C and O K-shell ionization edges of carbonyl sulfide. While the kinetic energy released in the reaction is mainly independent of the excitation energy, the angular anisotropy and momentum correlation clearly show deformation of the OCS molecule in the C1s−Pi state. The discovery of a two-body fragmentation channel SO+/C+ with a well defined angular anisotropy indicates the rapid formation of the CSO isomeric species.
