APPLICATION FIELDS

 
NMR REFERENCES
An aqueous solution of 0.01M NaBr is used as an external standard reference. The absolute frequencies are 25.053980 MHz for 79Br and 27.006518 MHz for 81Br 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).
