Abstract
The ^13^C n.m.r. spectra of some dimeric Catharanthus alkaloids are reported and assigned. Methods devised to aid in the assignment of resonances in complex molecules are described. The ^13^C n.m.r. spectra of several derivatives of vinblastine are discussed.

## Abstract ^13^C n.m.r. spectra have been measured for 39 compounds with branched structures including carboxylic acids, their methyl and ethyl esters, nitriles and chlorinated esters. The results obtained indicate that the ^13^ C n.m.r. technique is applicable to structure assignment of acids and
## Abstract The ^1^H and ^13^C spectra of fluorene, fluorenone, phenanthrene and their 4βmethyl and 4,5βdimethyl derivatives have been examined. To complete the analyses for fluorenone and 4βmethylfluorenone, ^1^H spectra were recorded at 270 MHz. The results from the ^1^H spectra permitted unequiv
## Abstract The ^13^C chemical shifts of several alkyl and phenyl substituted pyrylium perchlorates, together with related pyridine and pyridinium salts, are reported. The shifts in the isoelectronic series benzene, pyridine, pyrylium cation correlate well with charge densities calculated by INDO M
Several petroleum-derived materials have been structurally characterized in terms of their hypothetical average molecules using a combination of 1 H and 13C n.m.r. spectroscopy. Steps were taken to ensure that reliable 13C n.m.r. data were obtained, including adding a relaxation agent, chromium acet
## Abstract ^13^C n.m.r. spectra of a series of __N__,__N__βdisubstituted thioamides have been recorded and signal assignments were performed. Separate signals are observed for methylene groups fixed on the nitrogen atom. Since the carbon atom __syn__ to the thiocarbonyl sulfur resonates at higher
