## 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
