Abstract

If an electron beam is crossed by a molecular jet, the electrons are scattered (Fig. 1). At some distance from the scattering center (the nozzle, Fig. 1) one can observe the scattering pattern, a system of concentric rings (Fig. 2). These rings have varying intensities. The intensity distribution is a function of the structure of the scattering molecules. This is the basis of electron diffraction as a tool of structural chemistry.
