New light on the ‘split peak’ of alcohols

14 octubre 2014

For scientists probing the electronic structure of materials using RIXS, a persistent question has been how to account for «split peak» spectra seen in some hydrogen-bonded materials, but now researchers have performed an investigation of several types of liquid alcohols with RIXS and brought new perspective to this long-lasting debate. Researchers now show that the split peaks are tied to dynamic motions produced in response to the scattering X-rays themselves.
