Sulfur and chlorine K-shell x-ray absorption spectra of SCl2, S2Cl2, SOCl2, and SO2Cl2

The X-ray absorption spectra of dichlorosulfide (SCl2), dichlorodisulfide (S2Cl2), thionyl chloride (SOCl2) and sulfuryl chloride (SO2Cl2) have been recorded with synchrotron radiation in the regions of S 1s and Cl 1s excitation and ionization. Ionization current spectra of SOCl2 and SO2Cl2 in the Cl 1s regions are also presented. The main spectral features are assigned to K-shell excitations to σ* orbitals associated with the SCl, SS and SO bonds in these molecules.
