Abstract:
This talk provides an overview of current scientific capabilities and ongoing developments in chemical dynamics and spectroscopy at the ISIS Pulsed Neutron and Muon Source, Rutherford Appleton Laboratory, United Kingdom [1]. In particular, we emphasize the uniqueness of short-pulse spallation neutron sources to explore a broad range of structural and dynamical phenomena of chemical interest with unrivalled resolution, from relaxation phenomena and stochastic diffusion at sub-THz frequencies to atomic quantum thermometry using electron-volt neutrón spectroscopy [2]. These capabilities remain unique to ISIS, with a growing number of applications in physical and materials chemistry, including the study of novel charge-storage media and carbón-based functional materials [3]. We also illustrate the pivotal role currently played by first-principles materials-modelling methodologies to interpret increasingly complex neutron-scattering experiments, as well as parallel infrastructure developments for in-situ and operando studies under realistic conditions.
