Incommensurate Intermodulation of an Organic Intergrowth Compound Observed by Neutron Scattering

Abstract

The observation of an incommensurate diffraction pattern in urea inclusion compounds by neutron diffraction is reported. It reveals for the first time in these compounds the existence of all kinds of reflections expected for an intermodulated composite. The superspace analysis together with the temperature evolution of some characteristic reflections are presented.
