NMR REFERENCES
A saturated solution of K[NbCl6] in CH3CN is used as an external standard reference. Its absolute frequency is 24.476170 MHz with respect to 100.00 MHz of the TMS 1H signal. Also see IUPAC recommendations for reporting the NMR chemical shits of all nuclei relative to the 1H resonance of TMS (02JMR323-156).
