Summary

In this chapter, we introduce the basics of soft x-ray absorption (XAS) and emission spectroscopy (XES), and resonant inelastic soft x-ray scattering (RIXS) followed by description of instrumentation including beamline, ensdtation, and spectrometer. Chemical cells are designed for in-situ electronic structure study of samples in gas or liquid environment. The application of XAS, XES, and RIXS on TiO2 crystals of rutile and anatase phases have yielded characteristic fingerprints that provide the information on geometric structure, bandgap, doping effects. A number of in-situ electronic structure studies are also addressed.
