3 Nuclei in 2 minutes

Nuclear Magnetic Resonance (NMR) spectroscopy is an invaluable analytical technique; the information from an NMR spectrum complements the information obtained from other types of molecular spectroscopy and in many cases it offers unique diagnostic information about the sample material. Benchtop NMR performs well when a quick analysis of a high-concentration sample is needed, demonstrated using the example of diethylfluoromalonate.

The X–Pulse 60 MHz NMR spectrometer has two frequency channels: one acquires spectra of ¹H and ¹⁹F and the other, ¹³C. The probe can be manually tuned and matched for optimal performance. In this example, the first channel was tuned to ¹H and then the pulse width was lengthened to ensure effective radiofreqency (RF) transmission for the ¹⁹F experiment
