Х Lab 11.pdf Lab 11.pdf INTRODUCTION The chemical and physical properties of substances are influenced by the way in which valence electrons are distributed and by the three-dimensional shape of the molecule or ion. X- ray and neutron diffraction, infrared, Raman and microwave absorption spectroscopy, as well as dipole moment measurements, are used to ascertain the three-dimensional structure of a substance. Thus, techniques are available which can identify the geometry of substances Results of...
