I-400 NMR Spectrometer

This 400 MHz Varian Inova NMR Spectrometer is designed for experiments of all NMR-active nuclei at various temperatures. This spectrometer includes a Four Nucleus+ probe which can observe 1H, 19F, 31P, or 13C without assistance from the facility staff, and can be tuned to observe other nuclei. This probe is also capable of decoupling two nuclei (1H, 19F, 31P, or 13C) while observing a third nucleus (1H, 19F, 31P, or 13C). This instrument, driven by a SunBlade100, is predominantly used by inorganic chemists.
