The oscillator strengths and integral cross sections (ICSs) of the valence-shell excitations of carbonyl sulfide (OCS) are the basic and important input parameters in explaining the astronomical observation of sulfur-containing species and modeling the chemical and physical processes in planetary atmospheres and interstellar space. In this work, the generalized oscillator strengths (GOSs) of the valence-shell excitations of OCS have been determined by high-energy electron scattering. The corresponding optical oscillator strengths of OCS have been determined by extrapolating the GOSs to the limit of the squared momentum transfer, K²→0. As an independent cross-check, the present optical oscillator strengths are compared with the previous photoabsorption and electron scattering results. Meanwhile, the present BE-scaled ICSs (herein B is the binding energy and E is the excitation energy) of the dipole-allowed excitations of OCS have been obtained by the BE-scaling method from a threshold up to 5 keV.
