Abstract
The X-ray absorption K-spectra of chlorine were investigated in gaseous and solid Cl2, HCl, CCl4, and CHCl3. The first absorption peak does not undergo any changes on passing from the gaseous to the crystalline state, while the group of maxima with lower wavelength undergoes extremely substantial changes. It is proposed that in both the gas and the crystal the first maximum indicates a transition of the K-electron to an antibonding molecular orbital containing the 3px-orbital of chlorine, while the short-wavelength region for the solid state indicates the presence of wide energy bands in the crystal.
