NMR and EPR

Molecular systems important to biology, environmental remediation and sustainability are studied using a suite of nuclear magnetic resonance (NMR) spectrometers with frequencies ranging from 300 to 850 MHz. A pair of electron paramagnetic resonance (EPR) spectrometers complement the capability. See a complete list of NMR and EPR instruments.

Description

Interfacial and in situ biology—Innovative NMR instrumentation and techniques for probing properties of macromolecular cellular assemblies and in situ and ex situ metabolic processes, as well as for exploring biological membrane proteins in the solid state. Unique EPR and variable-temperature NMR approaches to explore structure and properties of redox metal centers cell biology.

Environmental chemistry— EMSL offers a unique NMR system for radiological studies. Users can perform magic angle spinning of highly radioactive samples with a novel hermetically sealed 3.2mm NMR probe. These tools allow users to apply NMR techniques to critical areas of radiological research, including the study of radioactive waste processing and storage.

Interfacial and in situ chemistry—Leading-edge solid-state NMR probe technology to analyze and quantify properties of advanced energy materials, fuel cells and real-time catalytic processes. High power pulsed field gradient diffusion capabilities for liquid and solid samples.

EMSL offers unique and custom NMR and EPR tools, including probes for specialized studies.

  • NMR spectrometers, ranging from 300 MHz to 850 MHz for high-field liquid-state, solid-state and micro-imaging techniques
  • W- and X-band pulsed EPR spectremeter for probing metal centers in biological and materials systems
  • NMR metabolomics capabilities
  • Extreme-temperature probes, both high and low temperatures
  • Virtual NMR tools for remote access to spectrometer systems.
