Molecular-frame photoelectron angular distributions (MFPADs) in carbonyl sulfide at selected
photon energies above the sulfur 1s ionization threshold have been measured using a recently
developed vector-correlation experimental setup and theoretically calculated using the
time-dependent DFT method. For this linear molecule, the selection of the fragmentation
channel CO+ + S+ is an effective method to fix the molecular frame. The experimental results
are found in good agreement with the calculated MFPADs.
