The Department of Chemistry and Physics houses two nuclear magnetic resonance (NMR)
spectrometers, operating at 60 MHz and 400 MHz for teaching and
research. The NMR facilities are managed by Drs.
The EFT-60 is an Anasazi upgraded Varian permanent magnet NMR. The magnet is a 1.4 Tesla permanent magnet and operates at a nominal proton frequency of 60 MHz. The EFT-60 is housed in room S-052 and primarily serves the sophomore organic laboratory.
AC-250 (out of service)
The Bruker AC-250 is a superconducting NMR spectrometer. The field of the magnet is 5.9 Tesla and operates at a nominal proton frequency of 250 MHz. Our primary research instrument was previously a Bruker AC-250 high-field NMR spectrometer which was purchased in 1993 under an Instruction and Laboratory Improvement (ILI, now CCLI) program from the National Science Foundation. The AC-250 was decommissioned at the end of 2005 and has been replaced by the AVII-400.
Avance II 400
Our aging AC-250 NMR gave good service for nearly 13 years. However, we were fortunate enough to receive a grant from the NSF Major Research Instrumentation program for a new Bruker Avance II 400 MHz instrument which was installed in April 2006. The AVII-400 is housed in room S-034A and primarily serves the research community and upper level laboratory courses. The spectrometer is made available by internet-based access to the campuses of ISU, St. Mary-of-the-Woods College, and Rose-Hulman Institute of Technology.
