The high-field NMR laboratory operates five Bruker instruments for liquid and solid samples, and possesses a wide variety of probes, which permit the analysis of any magnetic nucleus using virtually any pulse sequence. The NMR laboratory is open to the entire research community at UMass and affiliated institutions, and instruments are available by reservation throughout the day and evening.
The NMR Laboratory houses the following instruments:

• AVANCE600
• ASX300
• DPX300
• DSX300
• AC200

The AC 200 is used primarily for 1D proton spectra. The DPX 300, which is equipped with a sample changer, pulsed field gradients, and a four-nucleus probe, offers automated operation for simplified access to routine 1D and 2D experiments, including indirect detection.

Advanced projects in liquids are performed on the AVANCE600. Observation of varous nuclei using broadband probes, studies of protein folding dynamics in water, 19F site positions in amino acid substituted receptor proteins, variable kinetics with change of counterion in palladium catalyzed polymerizations, polymer-polymer binding in supra-molecular structures, tacticity/regiospecificity of polypropylene from advanced Ziegler-Natta catalysts, and mechanism of copper catalysis are several of the ongoing research projects that rely on this instrument.

For solids analyses, the DSX 300 and ASX 300 spectrometers are equipped with a variety of probes for static, magic angle, and wideline applications for virtually any magnetic nuclide. Research projects include REDOR distance determinations in selectively enriched receptor proteins, determination of torsion angle in 13C-15N enriched amino acids by heteronuclear double quantum NMR spectra on unorientated samples, mobility of polypropylene chains in amorphous and crystalline phases, and 27Al–31P cross polarization in surface-modified zeolites.

All spectrometers are ethernet linked for easy transfer, storage, and off-line processing of data at remote sites. (27-30 LGRT, A428 Conte, 577-1428)
