Neutron scattering is a powerful technique to study stochastic motions in liquids but it requires an energy resolution well below the meV range. As a consequence, quasielastic studies are performed over very limited energy ranges, yet transport phenomena in liquids are inextricably related to a complex hierarchy of fast and slow relaxation processes. On the experimental front, a way forward is to have simultaneous access to higher-frequency motions so as to provide much-needed insight into the underlying nature of transport phenomena, particularly in complex and strongly associated liquids. The aim of the present proposal is to measure QENS and Raman spectra of N-methylacetamide as a function of temperature across its entire liquid range. With these data, we will explore the relation between diffusive motions and well-defined intermolecular modes in this biomimetic hydrogen-bonded liquid
