NMR Spectroscopy

Services

Measurement of small variations in radio-frequency nuclear magnetic resonances (NMR) leads to the elucidation of covalent structure, stereochemistry (including conformations), and dynamics.  We offer the following general capabilities and services:

  • All common PFG-2D techniques up to 600 MHz
  • Solid samples at 300 MHz or 600 MHz for 4-mm or 7-mm CPMAS rotors
  • Full range of common NMR nuclei (to Rh-103)
  • Variable temperature at 400, 500, and 600 MHz
  • Inverse detection probes at 500 and 600 MHz
  • Convenient routine NMR analysis via evening robot automation at 400 MHz
  • 10-mm probe at 400 MHz
  • Wide-bore at 400 MHz with imaging capability
  • Regular two-hour training classes on basic operations
  • Staff-assisted development of special experiments

Using the NMR Lab

  • User Training.  Researchers wanting access to the FACES online scheduling system or to use the instruments must have completed the training course offered by the NMR staff.  Individuals may sign up for training by contacting Dr. Azurmendi.
  • Sample Submission.  Occasional users and external concerns may submit samples to Dr. Azurmendi in Hahn 006 for analysis.  Samples must be completely labeled, and a submission form must be fully executed.  Service is generally provided on a "first come, first served" basis, but emergencies will get higher priority if possible. 
  • Cost Accounting.  Each individuals wishing to use an NMR instrument or to submit samples to the service center must have a current Interdepartmental Service Request (ISR) on file.  Instructions for creating an ISR through HokieMart may be found here.
