Maltitol was assigned unequivocally without any need for reference to model compounds by a combination of 2D, SIMPLE (secondary isotope multiplets of partially labelled entities) and DIS (differential isotope shift) NMR techniques. The combination of these three techniques is very powerful for the a

β¦ Synopsis
The complete assignment of the sugar and acetate 13C and 'H signals of sucrose octaacetate by homo-and hetero-nuclear 2D NMR is described, using the Jeenet (COSY) and relayed coherence transfer techniques and heteronuclear shift correlation via both one-bond and long-range couplings.

## Abstract The ^1^H and ^13^C NMR resonances for ractopamine hydrochloride have been assigned. H,HβCOSY and H,CβCOSY were used to assign the aliphatic moiety of the molecule and to correlate protons and carbons on the same ring system. Longβrange selective proton decoupling (LSPD) experiments were
## One-bond and long-range two-dimensional 'H-I'C NMR experiments allow the unequivocal assignment of 13C and 'H spectra. On this basis, previous assignments of 13C signals of grossularine-1 and -2 have been revised.
The complete assignments of 1 H and 13 C signals of 19 pregnenolone and progesterone haptens were accomplished using twodimensional NMR techniques.
