The High Field Nuclear Magnetic Resonance Facility is a resource that provides nuclear magnetic resonance services through either a staff operator or hands-on-use by individual researchers. Equipment includes three superconducting spectrometers--all fully multinuclear and with variable temperature and mass data storage capabilities.
A Bruker WM-360 spectrometer, operating at 360 MHz for proton observations, utilizes multinuclear probes for either 5 mm or 10 mm tube sizes. A second Bruker MSL-300 spectrometer, operating at 300 MHz for proton observation, is a wide bore system with probes for both high resolution and high power observation. The multinuclear probes will accommodate 5 mm, 10 mm, or 20 mm tube sizes. A magic angle spinning accessory for high resolution solid state experiments is also available. A number of two-dimensional and other multipulse experiments can be conducted on these two spectrometers.
The third spectrometer is a Bruker AMX-600 instrument operating at 600 MHz for protons. This unit provides high resolution spectroscopy of complex molecules, with experiments most often performed in the 2D-mode. The instrument is fully multinuclear with 5 and 10 mm broadband probes and a probe for reverse experiments.
Several Silicon Graphics workstations are available for off line processing.
The NMR facility is operated by two NMR applications specialists. Charges for University users range from $2.50 to $8 per hour on the lower field instruments and up to $25 per hour on the 600 MHz instrument. Services to researchers outside the University of Iowa are possible and encouraged. Commercial users are charged at rates three times the rates charged to University users.
