Abstract

A new method of differentiating between the different mechanisms operative for ^13^C solvent effects is proposed. This approach, in which the ^13^C solvent shifts of C‐1 of tert‐butylcyclohexane are selected for the reference solvent shifts, allows the study of ^13^C solvent shifts measured from an internal TMS reference. Using this method, the solute factor related to the van der Waals contribution can be estimated, and specific solvent effects other than the van der Waals effect can also be detected.
