Investigation of Nuclear Motion by Electron Diffraction

Abstract

IT has long been known that the amplitude of nuclear vibrations in free molecules could be studied by electron diffraction if sufficiently accurate intensity measurements were made. Several years ago, Karle and Karle¹ developed the first successful experimental procedure for investigating nuclear motion. Since that time results for a number of molecules have been obtained, both by the Karles and by this laboratory. It is hoped that such information will prove useful in studies of potential fields of molecules, and will also serve to help in the interpretation of diffraction patterns of more complicated molecules with similar interatomic linkages.
