Angle-resolved sulfur 2p photoelectron spectra from the OCS molecule are re
ported in very high electron and photon energy resolution. The measurements
reveal significant differences in the angular distributions of ejected ele
ctrons associated with different core-level ionic multiplet states. A conco
mitant theoretical analysis relates these data to the perturbing effects of
spinorbit and molecular-field splittings, and indicates that the measured
angular distributions in high resolution provide a new and sensitive probe
of the molecular body-frame environment in the absence of explicit sample a
lignment.
