The quantitative importance (several ppm) of the effect of solute–solvent van der Waals' interactions on the13C chemical shift is shown for a non polar solute,n-pentane, in solution in 17 solvents and in the gas phase. The van der Waals screening constant term is discussed in respect to...
Thanks to model molecules, the chemical shifts were specified in 13C NMR for all carbon atoms with similar groups.doi:10.1002/macp.1984.021850920Jean Marie BessièreBernard BoutevinMohamed TahaDie Makromolekulare Chemie
