Electron Diffraction measurement on a single, stable, solid, crystalline sample of 10 nm minimum dimension in one direction, preferably 200-300 nm in the other directions. Deliverable will be the diffraction data as a normalized intensity file, structure solution and kinematic refinement, molecular structure, crystallographic files (.lst, .res, .ins, .fcf, .cif), and crystallographic tables, including molecule drawing and atom coordinates.
