Calculations of the dependence of 13 C chemical shifts on the dielectric constant, ϵ, of the medium are reported using the INDO/S parameterized version of Pople's method together with the solvaton model. Satisfactory agreement with the available experimental data is obtained. The rather sensitive dependence of chemical shift upon ϵ suggests that polar solute—solvent interactions in aprotic media should be taken into account when considering 13 C chemical shifts.
