Refinement of linear polymer crystal structures determined from electron diffraction data

The reliability of linear polymer structures determined by using electron diffraction data is investigated. The results of n ‐beam dynamical calculations and kinematic calculations which take account of crystal bending are compared with experimental structure factors for five published structures. In specific cases, both dynamical scattering and crystal bending effects are found to be important. Finally, guidelines are given for obtaining electron diffraction data which are optimal for structure solution.
