SCSB Nuclear Magnetic Resonance (NMR) Spectroscopy Laboratory
The laboratory hosts three high-field NMR spectrometers at the facility:
- Bruker Avance III 800 MHz spectrometer with a 1H⁄ 2H ⁄ 13C ⁄ 15N TCI cryoprobe
- Bruker Avance III 750 MHz spectrometer with a 1H ⁄ 2H ⁄ 13C ⁄ 15N TCI cryoprobe
- Bruker Avance III 600 MHz spectrometer with a 1H ⁄ 2H ⁄ 13C ⁄ 15N ⁄ 31P QCI cryoprobe
These instruments are capable of various multi-dimensional heteronuclear 1H ⁄ 2H ⁄ 13C ⁄ 15N ⁄ 31P NMR experiments. For the 750 MHz spectrometer, a diffusion broadband (DiffBB) probe capable of generating up to 270 gauss/cm field gradients is also available for diffusion experiments on various ions (e.g., 23Na+, 7Li+,19F-, 133Cs+). For stability of power supply, high-capacity UPS units protect the NMR spectrometers. A Cryomech LHeP22 helium recovery system recovers helium gas from the three NMR magnets and liquefies it for reuse, which reduces operating costs for the NMR equipment.
