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.
