Instrumentation

The NMR Facility houses four NMR spectrometers: the Bruker Avance III HD 400 (B400), the Varian INOVA 600 (I600), the Bruker Neo 600 (B600) and the Varian Infinity Plus 400 (I+400). The B400 is used exclusively for liquids NMR experiments, the I600 and B600 are used primarily for liquids experiments, but are capable of performing NMR experiments on solids, and the I+400 is used exclusively for solid-state NMR experiments.

The Bruker AvanceIII HD Console, Autosampler and Magnet.

Bruker AVIII HD 400 (B400) Utilizes an H/FX Bruker 5mm SmartProbe with Automated Tuning and Matching (ATM) Bruker SampleMail with 24-position SampleCase autosampler for automated usage. Samples are submitted to the sample queue and run in sequential order. Capable of acquiring 1D 1H, 19F, 31P-109Ag NMR spectra in automation. Capable of acquiring 2D 1H-{19F,31P-109Ag} NMR spectra in automation. Room-temperature experiments only. Utilizes CentOS 7.2 and Bruker's Icon 5 NMR software package. Ideal for beginners or infrequent users of the NMR facility.

The INOVA 600 Console and Magnet.

Varian INOVA 600 (I600) Utilizes a direct detection Auto-XDB probe capable of performing 1D and 2D NMR experiments involving 1H and 13C without modifications to the probe. Indirect and detect detection of odd-nuclei, such as 11B, 29Si, 77Se. Walk-up instrument. NMR time on the instrument must be booked using the FACES website. Time is limited to a maximum of 2 hours on weekdays from 9:00 am to 6:00 pm. Variable-temperature NMR experiments from -25 °C to +100 °C. Low-temperature experiments do not require cryogens for cooling. Capable of performing solid-state NMR experiments with a 3.2mm MAS HXY probe. Utilizes CentOS 6.8 and Varian's VnmrJ 4.2A NMR software package.

Bruker Neo 600 (B600) Utilizes an H/FX 5mm Bruker iProbe with Automated Tuning and Matching (ATM) Bruker SampleMail with 24-position SampleCase autosampler for easy sample managemet. Capable of performing 1D and 2D NMR experiments involving 1H, 19F, 13C and 31P without modifications to the probe. Indirect and detect detection of odd-nuclei, such as 11B, 29Si, 77Se. Walk-up instrument. NMR time on the instrument must be booked using the FACES website. Time is limited to a maximum of 2 hours on weekdays from 9:00 am to 6:00 pm. Solid-state NMR experiments can be performed using either a Bruker 4mm MAS HX iProbe, a Phoenix 2.5mm MAS HX probe or a Phoenix 5.0mm statix HX probe. Utilizes CentOS 8.8 and Bruker's TopSpin 4.1.4 NMR software package.

The Bruker 600 Console, Magnet and Autosampler

Varian Infinity Plus 400 (I+400) Wide-bore magnet used exclusively for solid-state NMR experiments. Six Varian/Chemagnetics probes available for use: 3.2mm MAS HX, 4.0mm MAS HXY, 5.0mm MAS HFXY, 7.5mm HXY, 9.5mm HXY, static 5/10mm HX. 3-channel spectrometer with two high-power (kW) broadband amplifiers, plus high-power proton and fluorine amplifiers. Depending on the probe, variable-temperature NMR experiments can be performed from -140 °C to +250 °C. Utilizes Solaris and Chemagnetics' Spinsight 4.2.3 NMR software.
