Neutron Scattering Studies of Host-Guest Interaction in Zeolites

Neutrons are coupled with all the degrees of freedom of the molecules, and particularly suitable to study molecular dynamics. They provide at the same time spatial and dynamical informations and allow a good representation of the guest behaviour in the host topology. Experiments have shown the mobility and diffusivity of protonated molecules (CH4, H-2 and HD) and the location of several hydrocarbons in zeolite crystals.
