Probes equipped: 

    1. Two Bruker 7 mm CP MAS probes. 
    2. One Bruker Wide line probe 
    3. One Chemagnetics 7.5 mm CP MAS probe. 
    4. One Bruker 10 mm liquid probe..

The AM 300 Bruker spectrometer was heavily modified to perform a variety of solid state NMR experiments. The system was also updated with the TECMAG. 

Probes equipped: 
    1. One Bruker 7 mm CP MAS probe. 
    2. One Bruker 4 mm CP MAS probe. 
    3. One 5 mm Bruker liquid probe. 
    4. Two 10 mm Bruker liquid probes.

A 500 MHz spectromter with Bruker UltraShield magnet (the first wide bore 11.7 T magent installed) was installed at Caltech in December of 1998. The spectrometer is equipped with three rf channels and a triple resonace 4 mm probe from Bruker:

   1. One 4mm Triple Resonance probe.
   2. One 4mm Double Resonance Extended VT probe
       (-120 C - 300 C)
   3. One 7mm CPMAS probe for low gamma nuclei
      (20 MHz-100 MHz)
   4. One 10 mm solution probe.
   5. One 2 mm probe (Max spinning ~ 50 kHz)
