Electrochemistry Of C82: Relationship To Metallofullerene Electrochemistry, Paul Burbank, James Gibson, Harry Dorn, Mark Anderson
Mark R. Anderson
Square-wave voltammetry of C82 in pyridine solutions containing 0.10 M tetra-n-butyl ammonium perchlorate indicates that C82 is reduced in four one-electron steps prior to the onset of electrolyte decomposition. The first reduction occurs at potentials positive of the reported first reduction potentials of other empty cage fullerenes, and at approximately the same reported potential for the first reduction of the endohedral metallofullerenes La@C82 and Y@C82. No oxidations were observed for the C82 under these conditions.

Polarization modulation infrared reflection absorption spectroscopy (PM-IRRAS) is used to study the structure of octadecanethiol, tetradecanethiol, and decanethiol monolayers in the presence of air, deuterium oxide, and acetonitrile-d3. It is found that the structure of the monolayer is dependent on both the adjacent environment and the initial structural order of the monolayer. In the D2O solutions, spectral changes are similar for the three monolayers and are characteristic of interaction predominantly between the solvent and the terminal portion of the monolayers. This correlates with electrochemical capacitance measurements that indicate little permeation of the aqueous electrolyte in the monolayer, even with the …

This progress report describes the development and student use of World-Wide-Web-based prelaboratory exercises in senior-level Instrumental Analysis during the 1995 Fall semester. The laboratory preparation exercises contained hypermedia tutorials and multiple-choice questions that were intended to familiarize the students with the experiments and instrumentation before their laboratory session. The overall goal of our work is to explore ways in which computer and network technology can be applied in education to improve the cost-effectiveness and efficacy of teaching.
