1 The accuracy of the calculated NMR chemical shift of the nominal but non-equivalent phenyl carbons C(3)/C(7) and C(4)/C(6) (ortho and meta to the acid -C(1)OOH group) of GA may not be evaluated using the experimental measurements at room temperature. Carbon complement C3 Homo sapiens
2 We further recognised that the C NMR chemical shifts of the nominal phenyl carbons (C(3)/C(7) and C(4)/C(6)) encode information for intramolecular hydrogen bonding network formed by GA conformers. Carbon complement C3 Homo sapiens
