GRADUATE PROGRAMS

Analytical Instrumentation Facility

Several nuclear magnetic resonance (NMR) spectrometers, including a Varian Inova 600 NMR, a Gemini 300 NMR and a Gemini 200 NMR spectrometer are located in the Analytical Instrumentaion Facility. These give access to all presently known multiple pulse measurements on both liquid and solid specimens. The NMR instrumentation makes it possible to perform a diversity of experiments on molecular structure and dynamics and reaction mechanisms. Nuclei routinely observable are 1H, 2H, 7Li,11B, 13C, 14N, 15N, 17O, 19F, 23Na, 27AI, 29Si, 31P, 33S, 77Se, 89Y, 107Ag, and 195Pt, with many others accessible.

A Kratos MS25RFA GC/Mass Spectrometer is also available, which has undergone recent upgrading of its data acquisition and handling systems. This dual-sector mass spectrometer has both CI (chemical ionization) and FAB (fast atom bombardment) capabilities in addition to the conventional EI (electron impact) source. A Varian Century Series E-112 electron paramagnetic resonance (EPR) spectrometer is also located in this facility.

Ernest B. Yeager Center for Electrochemical Sciences (YCES)

The Ernest B. Yeager Center for Electrochemical Sciences (YCES) is an interdisciplinary center that promotes and coordinates teaching and research in electrochemistry in eight participating departments; biomedical engineering, chemistry, chemical engineering, electrical engineering and applied physics, macromolecular science, metallurgy and materials science, mechanical and aerospace engineering, and physics.

YCES includes 35 faculty, 15 postdoctoral research associates and visiting scientists, and 74 graduate students, the largest group of whom are in the Department of Chemistry. As an international center for electrochemical study, YCES attracts visiting scientists from many countries. Research in YCES is supported with funds from both government and industrial sources, which currently total $4.5 million annually. The research projects are in general highly interdisciplinary and take advantage of the expertise of faculty and students from the various participating departments. YCES has an extensive course program at the graduate level in electrochemistry offered through the participating departments, coordinates a lecture-seminar series throughout the year covering a wide range of electrochemical topics, and arranges international symposia in electrochemistry.

Most of the extensive instrumentation for electrochemistry research which is associated with the interdepartmental YCES program is located within the Department of Chemistry. This includes a LEED-Auger-ESCA (electron spectroscopy chemical analysis) system; an automatic research ellipsometer; a UV-visible absorption/reflectance spectrophotometer; laser light scattering equipment for Brillouin, Rayleigh, and Raman spectroscopy; A Mössbauer spectrometer for passivation studies; ultrasonic absorption spectrometers; and vacuum sputtering and deposition equipment. In addition, there is a large array of conventional electrochemical equipment, including high-performance potentiostats, galvanostats, transfer function analyzers, oscilloscopes, and rotating disk-ring electrode systems.

Cleveland Center for Structural Biology (CCSB)

The Cleveland Center for Structural Biology (CCSB) is a joint venture between CWRU and the nearby Cleveland Clinic. It operates NMR instrumentation across campus including the systems located within the Analytical Instrumentation Facility. A Varian UnityPlus-600 MHz NMR spectrometer acquired in collaboration with the Medical School is located across the street from the Pytte Science Center. This NMR is equipped with numerous state of the art accessories including three broadbanded RF channels (all equipped with waveform generators for shaped pulses and GARP decoupling), a pulsed field gradient accessory for suppression of solvent resonances, and related software.

X-Ray Diffraction Facility

This facility, operated by Professor Protasiewicz is equipped with a state-of-the-art Siemens P4 X-ray diffractometer for structural determination by X-ray crystallography. Peripheral equipment for structure solution and graphics presentation includes a Nicolet Crystallographic Workstation with an HP Laserjet printer and a Silcon Graphics Indigo Workstation.
