Carbon‐13 NMR studies of substituted naphthalenes. I—complete assignments of the 13C chemical shifts with the aid of deuterated derivatives

Proton‐coupled as well as noise‐decoupled 13C NMR spectra of several substituted naphthalenes have been studied. Complete assignments of the 13C signals based on selectively deuterated derivatives and on the 13C1H coupling pattern have been made. For the methoxynaphthalenes, acetylnaphthalenes and naphthaldehydes the dominant conformations of the substituents have been deduced from the 13C chemical shifts.
