APPLICATION FIELDS

 181Ta NMR spectroscopy is applied on organotantalum compounds
NMR REFERENCES
A saturated solution of KTaCl6 in CH3CN is used as an external standard reference. Its absolute frequency is 11.989600 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).
