A total of 37 absorption bands, lying between 3785 and 4805 Angstroem, have been observed during the pyrolysis of S2Cl2 at 750 K.These bands have been tentatively assigned to transitions between the XA state of S2Cl to an unidentified electronically excited state with vibrational frequencies ω1' = 480 cm-1 and ω2' = 407 cm-1.From this assignment it follows that the ground state vibrational frequencies are ω1 = 659 cm-1, ω2 = 600 cm-1, and ω3 = 336 cm-1.A simple molecular orbital diagram has been constructed from the frontier orbitals of S2 and Cl.The predicted changes in the bond strengths and bond angles between the ground state and the excited state are consistent with experimental assignments.
