C4OS (8) is prepared by matrix photolysis and by flash pyrolysis of the precursor molecule 4, C4S2 (12) by matrixphotolysis of 10, 11, and 13.Upon irradiation both 8 and 12 are split reversibly into C3S (9) and CO or CS.The IR and UV/Vis spectra of C4OS(8), C3S(9), and C4S2 (12) are reported.Quantumchemical calculations have been performed for the structures, harmonic vibrational frequencies, singlet-triplet gaps, and electronic transition energies 8 and 12. Key Words: Matrix isolation / Photochemistry / Flash pyrolysis / Quantumchemical calculations
