## Abstract The synthesis of six 1‐X‐ (X = OH, OCH~3~, OCOCH~3~, CH~3~, CHO and CN) phenanthrene derivatives with a ^13^C label at C‐1 is described. An analysis of the ^13^C^13^C spin coupling constants shows the importance of π‐interaction for the coupling constant transmission. Small ^13^C^13^C s

## Abstract A series of 7‐^13^C‐labeled __o__‐substituted toluene derivatives and carboxyl‐^13^C‐isocrotonic and crotonic acid were synthesized and studied by ^13^C NMR spectroscopy to obtain ^13^C^13^C spin‐spin coupling constants involving the labeled carbon. The __cis__ ^3^__J__(CC) values were
## 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 A series of alicyclic compounds with dihedral angles of 0°, 60°, 90°, 120° and 180° between a ^13^C‐labelled carbon atom and a carbon atom separated by three bonds from the label has been synthesized. The vicinal ^13^C^13^C spin coupling constants were measured, and from the results a K
## Abstract The ^13^C^13^C spin–spin coupling constants in natural abundance oxetane, thietane, cyclobutanone, bromo‐and chlorocyclobutane have been measured. Furthermore, the ^13^C isotope‐induced changes in the chemical shifts of the different ^13^C nuclei in the molecules mentioned above are re
## Abstract A series of (>90% isotopic purity) ^13^C‐labeled aliphatic alcohols of the general structure CCC^13^COH were synthesized and studied by ^13^C n.m.r. to obtain all ^13^C^13^C couplings involving the labeled carbon. The ^2^__J__(CC) values were small (<0.5 Hz) and contrast with the l
