The proton chemical shifts of 2-hydroxy-1,3propanediamine-N,N,N',N'-tetraacetic acid and 1,3propanediamine-N,N,N',N'-tetraacetic acid in 1 :I complexes with diamagnetic metal ions have been investigated as a function of the metal ion charge Z and crystal ionic radius r. The chemical shifts correlate
## Abstract A new combination of 1D HOHAHA and INEPT pulse sequences is proposed and tested on an antibiotic, amikacin disulphate. The sequence provides ^13^C NMR spectra of chosen structural subunits and thus facilitates the NMR analysis of oligomers.
