Although the subject of numerous investigations, the origins of 13C nmr chemical shifts are still not well understood.a In order to simplify the problem, we have examined a wide variety of halogen substituted (F,Cl,Br,I) compounds. The similarity of the C-X bond dipoles" should minimize contribution
## Abstract Proton‐coupled as well as noise‐decoupled ^13^C NMR spectra of several substituted naphthalenes have been studied. Complete assignments of the ^13^C signals based on selectively deuterated derivatives and on the ^13^C^1^H coupling pattern have been made. For the methoxynaphthalenes, ac
