About the service

The Magnetic Resonance (MR) Unit houses the Nuclear Magnetic Resonance (NMR), the Electron Paramagnetic Resonance (EPR), and the Magnetic Resonance Imaging (MRI) Labs.

The three MR methods are powerful spectroscopic and imaging techniques that provide information about the structural and chemical properties of molecules/systems. They are considered as several of the few non-destructive methods for analyzing structure, molecular dynamics, and anatomy.

The Magnetic Resonance (MR) Facility provides qualified researchers in the biological and chemical sciences for accessing state-of-the-art MR instrumentation for spectroscopy and imaging. At present, the facility operates 11 MR spectrometers of varying purposes and capabilities. The recently-installed highest-field Nuclear Magnetic Resonance (NMR) 1000 MHz (1 GHz) instrument, as well as the 800 MHz NMR spectrometer are largely devoted to solution structure, function, and dynamic studies of macromolecules; the recently-installed metabolomics-oriented 600 MHz NMR spectrometer is equipped with an automatic sample changer and provides support for the growing metabolomics/metabonomics consitutency at the Weizmann; the three lower field NMR instruments (300-500 MHz), located in the Sieff building, are mainly used for structural characterization of organic and inorganic molecules. The wide-bore 400 MHz vertical NMR is used for in vitro biological studies and Solid-State, MAS NMR; and the recently installed state-of-the-art 15.2 T (650 MHz) horizontal-bore scanner, as well as the 4.7 T (200 MHz) MRI scanners are utilized for in vivo spectroscopy and imaging of small animals, imaging of materials, and in vitro spectroscopy of perfused organs.    Two EPR (also known as the Electron Spin Resonance, ESR) spectrometers are used to obtain structural, functional, and dynamic information of systems that have unpaired electrons.  All of the spectrometers are multinuclear and are equipped with a large variety of probes, as well as surface and imaging coils that are available for use.
