e/Fluorine-19 NMR

Information
has gloss	eng: Fluorine-19 NMR (for nuclear magnetic resonance) is an analytical technique. 19F has a spin of 1/2, and a relative abundance of 100 %, making measurements very fast (comparable with 1H NMR). Integrals are reliable due to the lack of a nuclear Overhauser effect (fluorine forms one bond only). Fluorine-containing compounds are occasionally encountered in organic chemistry (fluorinated compounds are popular in pharmaceutical applications), and in inorganic chemistry (e.g. the trifluoroacetate anion or counter-ligand).
lexicalization	eng: Fluorine-19 NMR
instance of	(noun) a nonmetallic univalent element belonging to the halogens; usually a yellow irritating toxic flammable gas; a powerful oxidizing agent; recovered from fluorite or cryolite or fluorapatite atomic number 9, F, fluorine
