Eirich,istry, and Rheology, his first contributions were to the physical chemical characterization of polymers in solution, building on the work of Doty and Zimm including the techniques of osmometry, isothermal diffusion, electrophoresis, ultracentrifugation, flow birefringence, and viscosimetry.

M. L. Huggins,f crystals.. I soon found that many crystals of known atomic arrangement were 3-dimensional macromolecules, with the atomics in each crystal all bonded together by ordinary chemical (electronpair) bonds. With the aid of published x-ray data I deduced the previously unknown structure’ of quartz (SiO.

These investigators were confronted with the dilemna as to whether it was necessary for the complete molecule to be located within the unit cell. The reso
