New NMR Technology – Meet “Maggie”

Nuclear Magnetic Resonance (NMR) Spectroscopy is a powerful analytical tool well known to all organic chemists and to anyone that works in pharmaceuticals. By placing a sample dissolved in deuterated solvent into a strong magnetic field (roughly 4000x the strength of Earth’s magnetic field) and pulsing it with radio frequencies, the chemist is given an enormous amount of information from the identity and placement of functional groups to relative stereochemistry of diastereomers. Recently, Exemplify added NMR to our expanding list of capabilities.
