Abstract

^1^H chemical shift assignments are presented for 2‐methyladamantane, 2‐methylnorbornane (endo and exo) and 2‐methylnorbornene (endo and exo). Resonance assignment was achieved using a variety of 1D and 2D homo‐ and heteronuclear (^1^H–^13^C) experiments. The methyl group‐induced substituent chemical shift (SCS) is derived and the SCS of protons vicinal to this group is discussed.

## Abstract Complete ^13^C spectral assignments were made for 1‐ and 2‐R‐naphthalenes (R = Me, Et, __i__‐Pr, __t__‐Bu) in CDCl~3~ solution (5 mol%) by the use of 2D techniques including 2D INADEQUATE. Contradictory assignments from the literature were clarified and incomplete data completed. Substi

## Abstract A principal component analysis is applied to α‐monosubstituted ethyl acetates (YCH~2~CO~2~Et), where the observed chemical shifts for the α‐carbon atom, the carbonyl carbon, and the α‐hydrogen atoms are correlated with theoretically derived molecular properties, i.e. the partial charges

## Abstract The ^1^H chemical shifts of 124 compounds containing a variety of functional groups have been recorded in CDCl~3~ and DMSO‐__d__~6~ (henceforth DMSO) solvents. The ^1^H solvent shift Δδ = δ(DMSO) − δ(CDCl~3~) varies from −0.3 to +4.6 ppm. This solvent shift can be accurately predicted (
