Nuclear magnetic resonance (NMR) is a physical phenomenon in which nuclei in a strong constant magnetic field are perturbed by a weak oscillating magnetic field. This produces an electromagnetic signal with a frequency characteristic of the magnetic field at the nucleus.

One Dimensional NMR allows us to collect information on 1H, 13C, 15N, 19F, and 31P atoms. By combining 1H, and 13C NMR (carbon skeleton and H atoms), IR Spectroscopy (functional groups), and Mass Spectrometry, the identities of many organic compounds can be determined.

The Thermo Picospin 45 benchtop NMR (left) is currently used by students in Organic Chemistry courses. GGC also maintains an Anasazi 90 MHz NMR with more advanced features for student research activities.
