We request 5 days on VESUVIO to study atomic momentum distributions within the frameworks of a series of SixGe(12-x)O24 zeolites with the SOD framework. Neutron Compton-scattering data is to be collected for each of the Si, Ge and O atomic species in the framework, from which we hope to obtain information regarding the connectivity of the framework in the germanosilicates. This is a concept yet to be investigated on VESUVIO, but discussions with an instrument scientist (Dr. J. Mayers) concluded that measurement of the O momentum distribution should provide information on the atoms to which it is bound and hence the connectivity.
