APPLICATION FIELDS

 
NMR REFERENCES
An aqueous solution of 0.5M BaCl2 is used as an external standard reference. Its absolute frequency is 11.112928 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).
