Accurate chemical shift and coupling constant for 1- and 2-naphthyl derivatives were decipher by iterative full spin analysis. Each of the seven magnetically nonequivalent H2–H8 atoms in 1-naphthyl derivatives, or of the H1, H3–H8 atoms in 2-naphthyl derivatives were unambiguously identified by analyzing their intra- and inter-ring coupling constants at 300 MHz and by two-dimensional homo- and heteronuclear experiments at 750 MHz. 13C chemical shifts were also determined during this study, from where some literature ambiguities were resolved using long-range C–H correlations at 750 MHz. The complete proton nuclear magnetic resonance parameters are herein ascribed for the first time.
