Abstract : The titanium L sub II,III X-ray emission and absorption spectra (wavelength approximately 27.5 A) from pure metal, oxides, nitride, carbide and boride have been investigated using a plane crystal vacuum spectrometer with electron beam excitation and flow-proportional counter detection. Emission spectra were studied over a wide range of accelerating voltages and takeoff angles showing that satellite emission and self-absorption effects can significantly distort the band shapes and energy positions of intensity maxima. A replica of the L sub II,III absorption spectrum can be constructed solely from emission spectra afflicted with widely different amounts of self-absorption. The first two absorption maxima appear to reflect the crystal field splitting of the Ti 3d levels into d epsilon and d gamma bands. The L sub II,III emission spectra from the oxides, nitride and carbide exhibit an important cross-over transition from the 2p level of the anion to the L sub II and L sub III levels of titanium.
