Nuclear Magnetic Resonance Facility (NMR)

Department of Chemistry

nmr-facility


The Chemistry Department currently houses 6 NMR spectrometers:

There are three state-of-the-art Bruker Avance III NMR spectrometers, with proton frequencies of 300, 400 and 600 MHz. They were purchased in 2012, 2011, and 2011, respectively. These are used for mainly research, but also for teaching. A short introduction to NMR spectroscopy can be found here.

Furthermore, there are 3 Anasazi Eft-60 NMR spectrometers at 60 MHz proton frequency. These were purchased in 2015 and are mainly used for undergraduate teaching.

This NMR Facility has capabilities for solution-state, solid-state, rheo, diffusion, and MRI (magnetic resonance imaging).

We would like to encourage the use of these instruments as much as possible, for internal and external users. We offer different types of NMR service, including full service that includes making up the samples to NMR requirements after you submit the samples either personally or using some type of mail service, running the experiments, process and analyze the data, and send a report by email or by post. We also offer training and it is possible to register for access to the laboratory. We also want to offer NMR service for community colleges as we know that many of them do not have adequate in-house NMR machines (and not a lot of money either, but don't let this stop you from contacting us) and may want to have their students check about their progress in the chemical laboratory and make sure that their expected product was actually formed. Many of the samples can be processed the same day as they are received at the NMR laboratory. This ensures that feedback is received is a timely fashion. Please contact us to discuss your experiments.

The main NMR Facility is located in the basement of the Physical Sciences building (PS 13) and is open to authorized users around the clock. Remote data access within the university is possible. Please read the operation instructions for the Bruker instruments and the operation instructions for the Anasazi instruments.

Bruker Avance III 600 MHz NMR 

The Avance III 600 is a three channel system with Z-axis gradients that is capable of performing experiments on both solids and solutions. Three probes cover a wide range of experiments.

Bruker Avance III 400 MHz NMR

The main workhorse instrument for most users. There are three solution-state NMR probes available for this instrument. It is possible to observe a wide range of nuclei, ranging from high sensitivity observation of proton, carbon, phosphorous, and fluorine to allowing observation of a large number of more exotic nuclei. This instrument is set up for rapid throughput of routine samples. It is capable of performing most modern liquid phase NMR experiments including state of the art two- and three-dimensional experiments with pulsed field gradients. It is available to departmental users to solve structural problems requiring high resolution capabilities.

Bruker Avance III 300 MHz wide-bore NMR

Several NMR probes are available for this instrument that make it especially versatile and capable of studies in solution, solid, rheo, diffusion and MRI (magnet resonance imaging).

Anasazi Eft-60 NMR

These three NMR spectrometer have proton and carbon capabilities in 1D and 2D. The proton resonance frequency is at around 60 MHz. A wide array of experiments are available and new ones are being prepared. These instruments are mainly used for undergraduate teaching.

Variable temperature operation is available on all three Bruker spectrometers. The three Anasazi Eft-60 NMR spectrometers employ a permanent magnet that needs to be kept at constant temperature. Although it is possible to adjust the temperature, we prefer to keep the temperature constant to avoid temperature-related drifts of the magnet.
