## Abstract One methyldecahydroisoquinoline and some octahydroโ and decahydroโisoquinolone derivatives were studied by ^13^C NMR. The configuration of these products was deduced by comparison of the experimental chemical shifts and the calculated values. Conclusions could thus be reached on the con
The vicinal "C-"P couplings in the C--C==C-P fragment of alkenephosphonates (-8Hz for a cis-and -22Hz for a trans-orientation of the respective nuclei) are a reliable and convenient parameter for the determination of the EZ configuration of these and analogous compounds.
## Abstract ^13^C NMR spectroscopy was used to investigate the structures of a series of pure isomeric cresylic novolak resins. Chemical shifts were measured and assigned, and end groups were distinguished from the central repeat units of the chains. Based on these measurements, the number average
