Abstract
We have measured the neutron scattering from 1-butyl-3-methylimidazolium chloride (bmimCl), which is known as a prototype room temperature ionic liquid. The temperature scan of the elastic neutron scattering showed that glassy bmimCl has a fast β relaxation appearing above T g as observed in many of molecular and polymer glasses. The quasielastic neutron scattering data of liquid bmimCl showed that the motion of bmim + ions is regarded as a simple diffusion. The activation energy calculated from the temperature dependence of the self-diffusion coefficients is smaller than that of the intramolecular rotation of butyl-group. This result indicates that bmim + ion is very flexible and stabilizing the ionic liquids entropically.
