## Abstract A summary of all the one‐bond carbon–carbon spin–spin coupling constants, Known up to the beginning of 1980, is given in diagrammatic form.
## Abstract Endocyclic one‐bond ^13^C^13^C spin–spin coupling constants in a series of cubane derivatives were recorded. The values measured using the INADEQUATE pulse sequence were found to be insensitive to the nature of the substituent, fall in a narrow range (27–30 Hz) and are comparable to va
## Abstract ^13^C^13^C spin–spin coupling constants have been measured for a series of variously substituted ethenes. The largest ^1^__J__(CC) value, 172 Hz, was found in chlorotrifluoroethene and the smallest, 45.3 Hz, in tris(trimethylsilyl)ethene, which covers a range of 127 Hz for the ^1^J(C
## Abstract Measurements of one‐bond carbon–carbon coupling constants, ^1^__J__(C, C), were performed for two series of compounds, alkyl‐substituted cyclopropenes and cyclopropanes. The experimental data were complemented by a set of DFT‐calculated __J__ couplings for the parent cyclopropene (**1**
