The one-, two-, and three-bond deuterium isotope effects (<SUP>1</SUP><I>Δ</I>, <SUP>2</SUP><I>Δ</I>, and <SUP>3</SUP><I>Δ</I>) on the <SUP>13</SUP>C chemical shifts of 3-substituted pyridines are reported. <SUP>1</SUP><I>Δ</I>, <SUP>2</SUP><I>Δ</I>, and <SUP>3</SUP><I>Δ</I> are correlated with the <SUP>13</SUP>C chemical shifts of the observed carbons. <SUP>1</SUP><I>Δ</I>, show a linear correlation with the <SUP>13</SUP>C chemical shifts with a positive slope. On the other hand, <SUP>2</SUP><I>Δ</I> and <SUP>3</SUP><I>Δ</I> show linear correlations with the negative slopes. They can thus be interpreted in terms of the π-electron density change by the substituent and the electron release effects by carbons one and two bonds apart from deuterium, respectively.
