Abstract : Major changes, caused by chemical combination, were observed in the soft X-ray L emission spectra of potassium, chlorine and sulfur. For the simple chlorides the chlorine L2,3 band at about 68 A increases in wavelength as the ionic character of the chemical bond decreases. The sulfur L spectrum from elemental sulfur and the sulfides consists of a 3s and a 3d band and is in the 77 to 85 region. This spectrum changes considerably in the sulfates with the 3s band completely disappearing and the addition of a 3p band. The relative merits of the stearate soap film crystal for use in the 40 to 100 A region are also discussed. Results were obtained using a flat crystal vacuum spectrometer with electron beam excitation and flow proportional counter. (Author)
