NMR Spectroscopy

The NMR lab contains three spectrometers: a Bruker AVANCE II 600MHz, a Bruker AVANCE 500MHz and a Bruker AVANCE III 300MHz.

All instruments are user run with training provided by research assistants and are available 24 hours per day, seven days per week. There is also a sample service for infrequent users. All data workup is done off-line from the instruments on networked PCs utilizing various software packages. One and two dimensional experiments are available with menu driven data acquisition and macro driven data workup.
