The high field spectrometer is a Bruker WB750, operating at 17.6T (proton resonance frequency 750 MHz) with a 89 mm clear bore inside the room temperature shim coil assembly. It features AVANCE electronics with three rf channels and the following assortment of NMR probes.

1. Two-channel (H-X) 2.5 mm MAS probe; maximum spin rate 35 kHz; VT range ~ -50 C ( spinning @ 30 kHz, -90 C @ 10 kHz) to ~ +120 C.


2. Three-channel (H-XY) 4 mm MAS probe; maximum spin rate 12 kHz; VT range ~ -70 C ( spinning @ 10 kHz) to ~ +120 C.


3. Two-channel (H-X) 3.2 mm MAS probe; maximum spin rate 18 kHz; VT range ~ -80 C ( spinning @ 10 kHz) to ~+120 C.


4. Two-channel (H-X) Broadband static probe; replaceable coils; VT range ~ -150 C to ~+150 C.


5. Two single channel, prototype low-frequency probes with replaceable components; VT range ~ -120 C to ~+120 C.

The 7.05 T spectrometer (Oxford 89mm bore magnet) is driven by Bruker AVANCE electronics, and features the following probes.

1. Two-channel (H-X) 2.5 mm MAS probe; maximum spin rate 35 kHz; VT range ~ -50 C ( spinning @ 30 kHz, -90 C @ 10 kHz) to ~ +120 C.
