✦ Synopsis
Full 13C NMR shift assignments have been made for both the sterculate and malvalate moieties in the seed oil from Sterculia fi~etida, and the chain distribution has been determined from quantitative NMR measurements. The proportion of malvalate is not significant at the inner chain position.

## Abstract ^13^C n.m.r. spectra of some substituted isoxazoles have been examined to ascertain the reactive site in the metallation of 4‐substituted 3,5‐dimethylisoxazoles. The results obtained indicate that metallation occurred exclusively at the C‐5 methyl.
## Abstract The combination of solid‐state nuclear magnetic resonance (NMR) techniques is very helpful for examining the behavior of heterogeneous amorphous polymers. With the magic‐angle spinning (MAS) technique, employing special conditions, only the mobile fraction of the molecule can be assigne
C chemical shifts and ''P,l'C spin-spin coupling constants are reported for six model phosphinates and eight synthetic phosphinolipids. The complex spectra of the synthetic phosphinolipids could be assigned from increments and couplings derived from the model compounds. Based on these investigations
## Abstract ^13^C chemical shifts are reported for a series of 2‐substituted 1,3‐dimethylbenzenes: comparisons of these values with those for the corresponding monosubstituted benzenes reveal, in some cases, large differences in the __para__‐carbon substituent chemical shifts, which are attributabl
## Abstract Carbon‐13 NMR chemical shifts are reported for six angular and one linear dichloropyridoquinolines in CDCl~3~. The chemical shift assignments have been made using model compounds, fully coupled spectra, selective proton decoupling and results from lanthanide shift studies. Chlorine subs
