Sulphur molecule , emission from

Hydrogen Sulphide.—Ion-molecule reaetions in methanol and H2S have been studied using a photoionization quadrupole mass spectrometer the proton affinity of H2S was determined. The sulphur emission and K absorption spectra from gaseous H2S have been measured. The spectrum comprises four peaks and the absorption spectrum three peaks that are of decreasing energy with increasing photon energy. 

Sulphur Dioxide. The. ST-ray emission and absorption spectra of sulphur in the SO2 molecule have been investigated both experimentally and theoretically. The spectra are linked energetically, thus making possible an analysis of iJie arrangement of occupied and free levels in the molecule. The relative positions of the energy levels obtained from the JT-ray spectra compare favourably with those obtained by theoretical calculations. The electronic structures of SO2 and SO have been investigated within the framework...
