The brand new Bruker ASCEND III HD 400MHz (9.4T) wide bore (89mm) spectrometer is available for solid-state NMR experiments. Also featured is a (+/-) 750 Gauss sweep coil enabling the possibility of high field dynamic nuclear polarization (DNP) experiments once a microwave source is aquired.

The three channel spectrometer is currently equiped with following probes:

• a 4mm MAS triple resonance broadband X/Y/H probe

     -- H channel: ¹H (400MHz) only

     -- X channel: ²⁰⁷Pb (81 MHz) - ³¹P (171 MHz)

                           ¹⁷O (43 MHz) - ⁸⁷Rb (132 MHz)

                           ¹⁵N (30.5 MHz - 42.5 MHz)

                           w/47pF shunt-capacitor

     X/Y pairs: ³¹P/27Al, ¹³C/¹⁵N-²H

• a 2.5mm MAS triple resonance broadband X/F/H probe

     -- H channel: for both ¹H (400MHz) and ¹⁹F (376MHz) (simultaneous tuning)

     -- X channel: typically ¹⁷O (43 MHz) - ¹¹⁹Sn (150MHz) (No ⁷Li and ³¹P)

     w/47pF shunt-capacitor: 31.6MHz - 45.5MHz (¹⁵N)
