An interesting family of Cu (II)-framework (NOTT100 series) has been synthesized at the University of Nottingham by the group of research of Martin Schröder. Earlier studies on NOTT101 and NOTT102 have been combining neutron powder diffraction and inelastic neutron scattering techniques at NIST-CNR and ISIS-RAL. Despite similar wall chemistry, it has been proved that the pore morphology had a direct effect upon the interaction of the copper site with an unusual INS doublet centered at 9 meV. It is essential to understand the dynamics of H2 with the unsaturated metal center in order to design stronger H2 bonding. We propose an INS experiment on NOTT103 with a various loadings of para-H2 gas. The rotational transitions of para-H2 molecules should infer essential information on their local environment in particular the interaction potential of specific adsorption sites populated.
