## Abstract An equation correlating ^13^C NMR chemical shifts and the global van der Waals energy of the carbon atoms (rms deviation Ξ΄ β€ 2.6 ppm) in aliphatic hydrocarbons, alcohols and chlorinated derivatives was derived. Molecular mechanics calculations have been used to determine the global van
## Abstract The ^13^C NMR spectra of triangulanes, the unique class of hydrocarbons constructed from spiroannulated cyclopropanes, were analysed, and correlations were revealed between their structures and ^13^C chemical shifts. The procedure for the configurational assignment in triangulanes based
