WebCarbon-13 NMR satellite. Read. Edit. View history. Carbon satellites in physics and spectroscopy, are small peaks that can be seen shouldering the main peaks in the nuclear magnetic resonance (NMR) spectrum. These peaks can occur in the NMR spectrum of any NMR active atom (e.g. 19 F or 31 P NMR) where those atoms adjoin a carbon atom (and … WebPhosphorus-31 NMR spectroscopy is an analytical chemistry technique that uses nuclear magnetic resonance (NMR) to study chemical compounds that contain phosphorus. Phosphorus is commonly found in organic compounds and coordination complexes (as phosphines ), making it useful to measure 31 P NMR spectra routinely.
