AV-700

This high field instrument is specially equipped for high resolution solid state NMR studies though it can also perform solution state NMR studies with suitable probeheads and accessories. Currently this spectrometer has two MAS triple resonance solids probes that can receive 3.2 mm rotors and one twin X-channel MAS probe that can drive 2.5 mm rotors. This is the only solids capable spectrometer in the facility at present.
