## Abstract The synthesis of six 1โXโ (X = OH, OCH~3~, OCOCH~3~, CH~3~, CHO and CN) phenanthrene derivatives with a ^13^C label at Cโ1 is described. An analysis of the ^13^C^13^C spin coupling constants shows the importance of ฯโinteraction for the coupling constant transmission. Small ^13^C^13^C s
## Abstract A series of 7โ^13^Cโlabeled __o__โsubstituted toluene derivatives and carboxylโ^13^Cโisocrotonic and crotonic acid were synthesized and studied by ^13^C NMR spectroscopy to obtain ^13^C๏ฃฟ^13^C spinโspin coupling constants involving the labeled carbon.
