Hakon Hope, Chung-Li Lee, Katie Lindsay, Andre Maisonnat and Marilyn Olmstead for their critical contributions. 

Any reasonably heavy atom can serve as an anomalous scatterer if the appropriate wavelength of X rays is used. For neutrons, however, there are fewer atoms that scatter anomalously (for example, Li, B, Cd, Sm, Eu, Gd) and their high absorption may limit their use. If X-ray diffraction intensity data are sufficiently carefully measured, it is possible to determine absolute configurations even if there are no heavy atoms in the structure, although values of A/" are very small for the light elements. Results of determinations of absolute structure must come from laboratories with an excellent reputation for careful intensity measurement. For example, Hakon Hope has been able to assign absolute...
