Early on in my graduate education (under the influence of K. H. Jack) I witnessed the value of X-ray powder diffraction in its provision of valuable structural information. This was especially valuable in the fluorine chemistry that I was then pursuing, since opportunities for single crystal production (at least in the first twenty years of my work) were minimal. I quickly set about learning to index X-ray powder data, and to solve simple structures using well-measured intensity data. Indeed, my first structure was that of PdF2 (see Ref. 4) and was worked out with one of K. H. Jack s students, R. Maitland, acting as my mentor. 

SEC experiments were carried out on a Watters 150CV instrument (Waters Associates, Milford, Massachusetts, U.S.A.) equipped with both differential refractive index single-capUlary viscometer detectors. The solvent/mobile phase was H20/0.02% NaNs, at the flow rate of 1.0 ml/ min. Pump, solvent, and detector compartments were maintained at 50°C. Separation occurred over a column bank consisting of three analytical columns preceded by a guard column Shodex KB-G, KS-802, KS-803, and KB-804 (Phenomenex, Torrance, California, U.S.A.). Universal calibration was performed using a series of oligosaccharides (Sigma, St. Louis, Missouri, U.S.A.), and PuUuIan Standards (American Polymer Standards, Mentor, Ohio, U.S.A., and Polymer Laboratories, Amherst, Massachusetts, U.S.A.).
