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, acetylnaphthalenes and naphthaldehydes the dominant conformations of the substituents have been deduced from the 13 C chemical shifts.
