Rotational Mobility in a Crystal Studied by Dielectric Relaxation Spectroscopy. An Experiment for the Physical Chemistry Laboratory  Madalena S. C. Dionísio, Hermínio P. Diogo, J. P. S. Farinha, and Joaquim J. Moura-Ramos
In this article we present a laboratory experiment for an undergraduate physical chemistry course. The purpose of this experiment is the study of molecular mobility in a crystal using the technique of dielectric relaxation spectroscopy. The experiment illustrates important physical chemistry concepts. The background of the experimental technique deals with the concepts of orientational and induced polarization and frequency-dependent relative permittivity (or dielectric constant). The kinetic concepts of temperature-dependent relaxation time, activation energy, and activation entropy are involved in the concept of molecular mobility.

Self-Assembled Colloidal Crystals: Visualizing Atomic Crystal Chemistry Using Microscopic Analogues of Inorganic Solids  Neal M. Abrams and Raymond E. Schaak
Monodisperse spherical colloids spontaneously crystallize into close-packed crystals, in analogy to the simple crystal structures of many of the elements. Since colloids are orders of magnitude larger than atoms, students can directly observe crystal structure and behavior in a microscope using colloidal crystals. This laboratory exercise provides a modular series of materials science experiments appropriate for undergraduate chemistry and engineering majors. The individual modules include aspects of chemical synthesis (monodisperse SiO2 and polymer spheres), self-assembly (colloidal crystallization), and structural characterization through microscopy (optical and scanning electron microscopies) and optical spectroscopy (optical diffraction and UVvisible spectroscopy).
