The Illinois EPR Research Center  (http://rlb6000.scs.uiuc.edu/) 
An NIH-Supported Resource Center 
Welcome to the Illinois EPR Research Center (IERC) home page. The IERC is a research laboratory and national Research Resource started in 1985. Its major support is from the BTA program in the NIH National Center for Research Resources under grant P41-RR01811. It is located on the campus of the University of Illinois-Urbana-Champaign. Its Directors are Professors R. Linn Belford and Robert B. Clarkson 

What is EPR? (http://ierc.scs.uiuc.edu/epr.html) 
Electron paramagnetic resonance (EPR), also known as electron spin resonance (ESR) and electron magnetic resonance (EMR), is the name given to the process of resonant absorption of microwave radiation by paramagnetic ions or molecules, with at least one unpaired electron spin, and in the presence of a static magnetic field. EPR was discovered by Zavoisky in 1944. It has a wide range of applications in chemistry, physics, biology, and medicine: it may be used to probe the "static" structure of solid and liquid systems, and is also very useful in investigating dynamic processes.

The National Biomedical EPR Center (http://www.biophysics.mcw.edu/bri-epr/)  
The Electron Paramagnetic Resonance (EPR) Center at the Medical College of Wisconsin is the largest EPR facility in the nation with instrument capabilities for many types of EPR experiments. The ten spectrometers currently in operation have the capabilities for S, X, L, and Q band, ENDOR, ELDOR, Saturation-Transfer, Saturation Recovery, and multiquantum spectroscopy. The research conducted within the EPR Center include both technological innovation and application of new techniques to biological problems. The main areas of research are free radicals, spin labeling, metal complexes and metallo proteins. This center was founded in 1976 by a grant from the National Center for Research Resources of the National Institutes of Health, P41-RR01008.

The STDB is a database of over 9000 records of published Spin Trapping experiments. This data includes the experimental results and journal reference information. Users may search the database using any combination of several fields of data such as Spin Trap, radical molecule, solvent, text keywords, and hyperfine splittings. The resulting data is linked to the journal reference information.

Research Triangle Park, NC, USA 
The NIEHS has produced software for Electron Paramagnetic Resonance analysis since 1983. Originally, programs were written for the HP technical workstation that Varian supplied with their last spectrometers, but current programs are written for the IBM DOS, MS-Windows, and various UNIX workstation formats. This software is provided free to the EPR research community with the understanding that any resulting report either internally or externally distributed explicitly aknowledge this contribution.

The following is an attempt to encourage all interested scientists to use EPR in their research. It is aimed especially at researchers in Alberta, who will hopefully be able to use our excellent EPR facility and pay us lots of money for the privilege. 
The MRC Group in the Molecular Biology of Membranes has carried out extensive studies over recent years using electron paramagnetic resonance spectroscopy (EPR) to study biologically significant organic free radicals and transition metal enzyme prosthetic groups (for example in E. coli DMSO reductase). These studies have utilized an EPR spectrometer located in the University of Alberta's Faculty of Medicine which is operated by the MRC Group in the Molecular Biology of Membranes. This facility is now available on a cost-recovery basis to members of the university research community, biotechnology research companies, and the chemical industry.

EPR Research Group ETH Zurich (http://www.esr.ethz.ch/) 
The EPR Group is part of the Physical Chemistry Laboratory at the Chemistry Department of the Swiss Federal Institute of Technology in Zurich. Our research focuses mainly on the development of techniques and instrumentation in pulse EPR, but we also concern about applying our methods on interesting paramagnetic compounds. On this page you can find besides a short introduction to pulse EPR and pulse ENDOR a summary of our research we have done during the last few years.

 Research: Applications of ESR (http://ahudson.mols.sussex.ac.uk/res.html) 
 Electron spin resonance is a sensitive and specific technique for investigating paramagnetic species and has widespread applications in physics, chemistry, biology, and medicine. We are interested in both theoretical and practical aspects of the subject including spin relaxation processes and lineshapes and organometallic free radicals. A recent development has been the application of ESR to problems of environmental concern, including in vivo studies of damage to conifers from ozone, sulfur dioxide, and other phytotoxic pollutants, and the spin-trapping of free radicals produced in combustion processes. 
 

Wojciech Froncisz (http://www.mol.uj.edu.pl/user/froncisz/) 
Professor of Biophysics, M.Sc. - 1968 from the Moscow State University; Ph.D. - 1976; Habilitation - 1981; both from the Jagiellonian University, Visiting Professor at the Medical College of Wisconsin (over 8 years). Director of the Institute of Molecular Biology (1987-93). Corresponding Member of the Polish Academy of Arts and Sciences. Awarded in 1994 with a silver medal in recognition of his "benchmark contribution to EPR spectroscopy" by ternational ESR Society. 

Research summary: 
Main field of research is electron paramagnetic resonance (EPR) spectroscopy and its application to molecular biophysics, especially to studies of the structure and dynamics of biomolecules. Dr. Froncisz is involved in the development of EPR instrumentation for biophysical studies. Together with Dr. Hyde from the Medical College of Wisconsin (USA) they invented a new class of microwave resonators named loop-gap resonators. These resonators serve as very sensitive probes in EPR spectrometers operating in the range of 1 to 36 GHz. Recently a new pulse EPR spectrometer for saturation recovery studies of free radicals has been constructed in his laboratory. This unique instrument sets a new sensitivity standard in the saturation recovery EPR spectroscopy in the case of biological samples.

About Scientific Software Services 

Scientific Software Services was founded in 1988 with a single product, EPRWare, designed for data acquisition on a Varian EPR 
spectrometer. Since that time, we have added products for EPR simulation, linewidth deconvolution, EPR imaging, for all spectrometers 
and have enhanced EPRWare through several version. Our EPR products are in use around the world.
