One- and two-bond deuterium isotope effects (<SUP>1</SUP><I>Δ</I> and <SUP>2</SUP><I>Δ</I>) on <SUP>13</SUP>C chemical shifts of substituted benzenes are reported. The one-bond effects are correlated with the π-electron densities on the observed carbons, and the two-bond effects are correlated with the σ-electron densities on the observed carbons. There are no correlations between <SUP>1</SUP><I>Δ</I> and <SUP>2</SUP><I>Δ</I>. <SUP>1</SUP><I>Δ</I>s reflect the direct change on going from a C–H bond to a C–D bond, but <SUP>2</SUP><I>Δ</I>s reflect their indirect effect.
