AbstractQuenching of vibrational excitations in resonant inelastic X-ray scattering (RIXS) spectra of liquid acetic acid is observed. At the oxygen core resonance associated with localized excitations at the O–H bond, the spectra lack the typical progression of vibrational excitations observed in RIXS spectra of comparable systems. We interpret this phenomenon as due to strong rehybridization of the unoccupied molecular orbitals as a result of hydrogen bonding, which however cannot be observed in x-ray absorption but only by means of RIXS. This allows us to address the molecular structure of the liquid, and to determine a lower limit for the average molecular chain length.

In this study an analysis strategy towards using the resonant inelastic X-ray scattering (RIXS) technique more effectively compared with X-ray absorption spectroscopy (XAS) is presented. In particular, the question of when RIXS brings extra information compared with XAS is addressed. To answer this question the RIXS plane is analysed using two models: (i) an exciton model and (ii) a continuum model. The continuum model describes the dipole pre-edge excitations while the exciton model describes the quadrupole excitations. Applying our approach to the experimental 1s2p RIXS planes of VO2 and TiO2, it is shown that only in the case of quadrupole excitations being present is additional information gained by RIXS compared with XAS. Combining this knowledge with methods to calculate the dipole contribution in XAS measurements gives scientists the opportunity to plan more effective experiments.

AbstractCapillary X-ray optics is versatile, and it can be used with synchrotron radiation source, conventional X-ray source, laser-plasma ultrafast X-ray source, and so forth. Recently, the confocal X-ray technology based on capillary X-ray optics has become popular, and it has been widely used in X-ray fluorescence, X-ray absorption fine structure, X-ray diffraction, small-angle X-ray scattering, X-ray imaging, and X-ray scattering. This confocal X-ray technology has applications in many fields, including environmental monitoring, food science, life science, chemistry, physics, nanomaterials, nondestructive test, security check, and so on.
