Vibrational resonant inelastic X-ray scattering in liquid acetic acid: a ruler for molecular chain lengths
Abstract Quenching 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 R...
