description

Abstract Incoherent quasi-elastic neutron scattering (IQENS) data on liquid isomeric alcohols normal-pentanol (n-PeOH) and 2-methyl-2-butanol (2M-2BuOH) and on their mixture are presented. The diffusive motion of protons, as a function of temperature, is analyzed in the framework of the random jump diffusion model. The temperature dependence of the parameters obtained confirms the more “fragile” behaviour of the more sterically hindered 2M-2BuOH with respect to that of the linear n-PeOH.
