Quasielastic neutron scattering (QENS) from biomolecular systems, such as proteins, probes essentially the diffusive single particle dynamics of the hydrogen atoms. As far as the internal dynamics is considered, the motion of the hydrogen atoms exhibits both multiscale and quantum properties. Starting from the definition for the mean square displacement of a quantum particle, it will be shown how both aspects can be combined within a theory of QENS experiments, which is asymptotically exact for long times/low frequencies and for moderate momentum transfers.
