AI Article Synopsis

  • The study explores two interpretations of resonant inelastic x-ray scattering (RIXS) spectra of liquid water, focusing on structural environments versus core hole dynamics affecting spectral components.
  • By utilizing high-resolution RIXS in the OH stretch vibration energy region, researchers identified dissociative contributions at different excitation energies, revealing a complex behavior of spectral features.
  • At lower excitation energies, a pronounced dissociative feature appears, while at higher energies, this feature weakens, highlighting the importance of both interpretations for understanding RIXS spectra in liquid water.

Article Abstract

There has been a discussion on the interpretation of the resonant inelastic x-ray scattering (RIXS) spectra of liquid water in terms of either different structural environments or that core hole dynamics can generate well-resolved dissociative spectral components. We have used RIXS with high resolution in the OH stretch vibration energy part, at extremely high overtones going toward the continuum of full OH bond breakage, to identify the amount of dissociative contributions in the valence band RIXS spectra at different excitation energies. We observe that at low excitation energies, corresponding to population of states with strongly antibonding character, the valence band RIXS spectra have a large contribution from a well-resolved dissociative feature. Instead, at higher excitations, this spectral component diminishes and becomes a weak structure on the high-energy side of one of the spectral peaks related to the 1b state from tetrahedral configurations. This result brings both interpretations to be essential for the understanding of RIXS spectra of liquid water.
