APPLICATION FIELDS

 139La NMR spectroscopy has been applied on inorganic and organolanthanum compounds.
NMR REFERENCES
An aqueous sample of 0.01M LaCl3 is recommended as a standard. The absolute frequency is 14.125641 MHz with respect to 100.00 MHz of the TMS signal. Also see IUPAC recommendations for reporting the NMR chemical shits of all nuclei relative to the 1H resonance of TMS (02JMR323-156).
