A second method for the determination of absolute configurations, due to Walter C. Hamilton, involves a computation of R values for both the trial structure and its mirror image. The ratio of these two R values will show which structure is correct and will allow an assessment to be made of the reliability of the choice. Small and possibly insignificant differences in I hkl) and I[hkl) are included in this, however, and a few reflections with large differences should also be checked as described above in the first method. 

This paper was to have been prepared by Walter C. Hamilton. It is a matter of great sadness to us all that he has been taken from us. Aside from our personal loss, his absence has been a substantial scientific loss to this conference. I cannot feel that I am in any real sense a replacement for him. My paper by no means covers all that Walter Hamilton would have included, in view of his unique position at the forefront of many areas of structural crystallography as well as my own relative detachment from direct technical involvement in crystal-structure determination over the past few years.

The first step in a unimolecular reaction is the excitation of the reactant molecule s energy levels. Thus, a complete description of the unimolecular reaction requires an understanding of such levels. In this chapter molecular vibrational/rotational levels are considered. The chapter begins with a discussion of the Bom-Oppenheimer principle (Eyring, Walter, and Kimball, 1944), which separates electronic motion from vibrational/rotational motion. This is followed by a discussion of classical molecular Hamiltonians, Hamilton s equations of motion, and coordinate systems. Hamiltonians for vibrational, rotational, and vibrational/rotational motion are then discussed. The chapter ends with analyses of energy levels for vibrational/rotational motion.
