Nuclear Magnetic Resonance Center

Magnetic Resonance Center

The University of Akron Magnetic Resonance Center (MRC) is a jointly managed facility between the Department of Chemistry, the Institute of Polymer Science and Polymer Engineering and other departments. The Center consists of 9 NMR systems ranging from 200 MHz to 750 MHz, and is located in Knight Chemical Lab and Goodyear Polymer Science buildings. For details of the center, check: http://www.uakron.edu/chemistry/magnet/

These three instruments are available in the Goodyear Polymer Center 103A.

EQUIPMENT AT THE NUCLEAR MAGNETIC RESONANCE CENTER


Varian NMRS 500 (5 ch)

  • This is a Research grade 5 channel instrument equipped for double and triple resonance experiments in both solids and liquids. It includes a suite of probes to do essentially every useful permutation of triple resonance experiments, including 1H/13C/X (where X covers essentially the entire range of nuclear resonance frequencies). The instrument was purchased to perform diffusion experiments with high gradient strengths (120 Gauss/cm), and very high temperature (up to 250 deg. C) solution and solids experiments.
  • Instrument rates for UA users can be found on the Magnet Intranet Rates page. NMRS 500-02 GDYR 103a
  • The nature and variety of experiments which are performed on this instrument require that time be scheduled at least one (1) to two (2) weeks in advance. Contact lab personnel by Noon on Wednesdays to request instrument time for the following 2 weeks.

Varian NMRS 500

  • This is a Research grade 2 channel instrument for H/X double resonance experiments. It is equipped with a robotic sample changer, auto-tune and auto-shim capabilities for continuous unattended instrument optimization and operation. This instruments configuration will alternate between robotic operation of 10- and 5-mm dual broadband probes (based on demand).
  • For access to this instrument, please contact Dr. Dudipala for training and checkout. Once you have been checked out to operate this instrument, time can be reserved via the Intranet Scheduling page.

Varian MERCURY 300

  • This NMR instrument is a 300 MHz spectrometers equipped to observe 1H/19F and 13C/31P. In addition to routine 1-D 1H and 13C spectra, homo- and heteronuclear decoupling, APT, DEPT, COSY, HETCOR (Heteronuclear shift correlation), homonuclear-2DJ, NOE Difference and saturation experiments etc., can be performed.
  • This is intended to be walk up instruments for undergraduate and graduate student research. Only people who have been checked out by lab personnel are allowed to use the instrument.
  • These instruments are intended for routine walk-up access, however up to 30 minute time slots may be reserved between the hours of 8:00 AM and 5:00 PM.; two hour time slots can be reserved from 5:00 P.M. to 10:00 P.M., and up to 10 hours can be reserved between 10:00 P.M. and 8:00 AM.; Signup is via a reservation system accessible via the Magnet Intranet page.

The following five instruments are available in the chemistry department:

  • Inova-750 solids and liquids NMR spectrometer
  • Inova-400 solution NMR spectrometer
  • Gemini-300 solution NMR spectrometer
  • Inova-200 solids NMR spectrometer
  • CMC-200 triple resonance solids NMR spectrometer
