Magnetic Resonance Center
The Magnetic Resonance Center (MRC) at Boston College (BC) maintains three Varian/Agilent and two Bruker AVANCE NEO NMR spectrometers. The Varian/Agilent systems are at 400, 500 and 600 MHz with room temperature probes, while the two Bruker systems are at 500 MHz, and are equipped with helium and Prodigy CryoProbes. The Bruker instruments, which are the latest additions to the MRC, were funded by external grants from the NIH-S10 and NSF-MRI programs. In addition to the NMR spectrometers, the MRC also maintains a Bruker EMX-Plus EPR system with a cryogen-free variable temperature (VT) setup, as well as an ESR 5000 bench-top EPR spectrometer.
The instruments available at the MRC allow NMR users to observe most spin-active nuclei and perform nearly all state-of-the-art, multi-dimensional solution-state NMR experiments. Similarly, any required X-band EPR experiments can also be performed at ambient and low temperature settings, with MRC staff supervision. In addition to supporting the wide range of research programs of the BC faculty, these spectrometers are also used for teaching and outreach programs. The iLab Core Facility Management software is used for all reservation purposes, thereby ensuring the most efficient use of the facility’s resources.
In addition to the instrumentation and expertise of the MRC staff for consultations, all facility users are further supported by free access to the Mestrenova software for data processing, which can be utilized following a safe and seamless transfer of files to any personal device within the BC network. Users may also store data on the spectrometer computers; this data is backed up by the IT specialists at BC, who are always available to troubleshoot and resolve any technological issues.
Please note that all work performed in BC core facilities and recharge centers should always be appropriately acknowledged. If you are publishing or presenting data acquired in BC core facilities and recharge centers, please include the following statement in the Acknowledgement section of your manuscript/poster/presentation, "The authors would like to thank the Boston College <insert facility name> for assistance with the work presented in this paper/poster/presentation*."

The new departmental EMX-Plus EPR spectrometer from the Bruker Biospin Corporation is equipped with a cryogen free VT system that allows the samples to be cooled down to temperatures as low as 4.5 K. This instrument provides crucial support to research groups working on high-spin metal complexes containing iron or cobalt centers. Along with an ER 073 10” double-yoke magnet, this system has a Hall field controller and signal channel module that are both digital and ultra-high resolution, an X-band, solid state low noise microwave bridge and a high sensitivity probehead with an optical window for running CW-EPR experiments in X-band. The system runs on Xenon 1.1 acquisition software in a Linux environment, with WIN-EPR, WIM-SimFonia as well as the XSophe software package for the simulation of EPR spectra.
