Abstract
An equation correlating ^13^C NMR chemical shifts and the global van der Waals energy of the carbon atoms (rms deviation ฮด โค 2.6 ppm) in aliphatic hydrocarbons, alcohols and chlorinated derivatives was derived. Molecular mechanics calculations have been used to determine the global van der Waals energy.
