Nitrilotriacetic Acid Anhydride,1H NMR AND 13C NMR

learn nmr the simple way with simple molecules, two-four signals at a time with examples

PROTON NMR

1H(d6-acetone, 400 MHz): 

3.920(s, 4H), 
The two PLUS two  NCH2 protons of -NCH2-C=O-O on the ring

3.620(s, 2H); 

The two   NCH2 protons of -NCH2-C=O-OH on side chain


CARBON 13 NMR


13C(d6-acetone, 100 MHz): 

171.18, The single carbonyl carbon  of -NCH2-C=O-OH on side chain

165.51(2C),  The two  carbonyl carbons  of -NCH2-C=O- on the ring

54.79, The single N attached carbon  of -NCH2-C=O-OH on side chain

52.54(2C), The two N attached Carbons at   -NCH2-C=O-O on the ring




slow and steady wins the race
