Anisotropy of hexagonal boron nitride core absorption spectra by x‐ray Raman spectroscopy

What is it about?

B as well as N core excitation spectra of hexagonal boron nitride (h‐BN) have been studied by means of x‐ray Raman scattering (XRS) spectroscopy. Transitions from 1s core to σ∗ and π∗ states are completely distinguished by anisotropy measurements of XRS, thus making an unambiguous assignment to the symmetries of excited states and offering a sound basis to characterize h‐BN with core absorption spectroscopy.
