Lab Discription

This NMR laboratory is part of the Chemical Instrumentation Facility located in the Department of Chemistry of Iowa State University. The facility is partially funded by National Science Foundation and the Dean's office of ISU Science and Humanities. Although the primary users of the NMR facility are from the academic community within the University, the lab is open to researchers in other educational institutions and industry. The goal of the laboratory is to provide state-of-the-art NMR instrumentation for scientists in all possible research areas. The facility is housed in room 1708, Gilman Hall on the ISU campus.

The laboratory is equipped with four NMR instruments capable of handling a wide range of nuclei and techniques in both solution and solid states.

Bruker DRX-400 Spectrometer

This narrow bore 9.4 tesla instrument is equipped pulse-field-gradients (PFG), four channels, shaped pulse, digital filtering. Two 5 mm PFG probes, one triple resonance inverse with 2H/31P/1H/BB channels and the other normal geometry with 2H/1H/BB channels, are capable of handling the full range of nuclei, including fluorine. This instrument is principally used for multi-dimensional or other complex experiments. It was purchased in 1995.

Varian VXR-400S Spectrometer

This wide bore 9.4 tesla instrument, configured with a 5 mm switchable probe, is designed as a walk-on instrument for routine 1H/X observation. Users have the maximum of 10 minutes to use the instrument during primetime (1:00pm -5:00pm weekdays). For those experiments requiring longer time, users may reserve blocks of time one week in advance. It was made in 1989.

Varian VXR-300S Spectrometer

This wide bore 7 tesla instrument, configured with a 5 mm switchable probe, is designed as a walk-on instrument for routine 1H/13C observation. Users have the maximum of 10 minutes to use the instrument during primetime (8:00am-11:00pm weekdays, 8:00am-5:00pm weekends). For those experiments requiring longer time, users may reserve blocks of time at night in one week advance. This instrument was purchased in 1992.

Bruker AV-600 Spectrometer

This wide bore 14 tesla instrument is capable of doing both solution and solid experiments. The instrument is equipped with both 4mm and 2.5mm MAS probes, a static probem, and a 5mm inverse triple resonance solution probe. MAS probes (1H, 1H/44-122MHz, and 1H/30-80MHz) for high resolution solid This instrument is used for basic long-term experiments. It was purchased in 2006.

All NMR instruments have the variable temperature capability.
