The vibrations of hydrogen bonds

I present recent inelastic incoherent neutron scattering (INS) work involving the study of the H-bond vibrations. These vibrations have spectral consequences which are strongly dependent upon spectroscopic technique, and these will be indicated for IR and Raman, and detailed for INS. The vibrational dynamics of the simple FHF⁻ will be used by way of an example. These INS results demonstrate that the latest generation of neutron spectrometers provides new insights into H-bonding dynamics.
