Instruments
The Magnetic Resonance Research Center operates eight different nuclear magnetic resonance (NMR) spectrometers for liquids analysis ranging in magnetic field strength from 7.05 to 18.8 T, corresponding to proton resonance frequencies of 300 to 800 MHz, respectively. All of the spectrometers are multinuclear and a large variety of probes are available.
