Nuclear Magnetic Resonance Spectrometry

Chap 19

Identification of Compounds with NMRIdentification of Compounds with NMR

• Can be used organics, organometallics, andbiochemical molecules

• NMR alone is not sufficient for compound ID

• Corroborate with MS, IR, and UV-vis, and elemental analysis
