For this purpose, 13C NMR spectra of a large number of hydrocarbons and heterocyclic compounds were obtained and analyzed or partially analyzed. Several phases of these spectral investigations have been previously published(1–4); the work reported here is primarily concerned with hydroaromatic compoun...

Principal component analysis was applied to the 13C NMR chemical shifts of the seven carbon atoms of the norbornyl framework for 75 molecules. Two two-dimensional principal component projections are shown to be sufficient to distinguish the main electronic and steric substituent effects contributing to...
13C chemical shifts of tetramethylsilane (TMS) have been determined at infinite dilution in 16 solvents. As compared to the respective proton shifts, their magnitude is much higher and anisotropic shifts are of less significance. This is being discussed in view of the increasing use of TMS as ...
