摘要：

The origin of the three broad bands appearing in the dielectric spectra of molecular glass formers is tracked down to microscopic scales by means of neutron-scattering and molecular-dynamics simulations. Three distinct regimes are also seen in the neutron quasielastic spectrum and are shown to arise from well-separated time regions appearing in the single-particle dipole autocorrelation function derived from simulations.
