Abstract

Secondary deuterium isotope effects (IE) on the acidity (pKa) of glycine were measured by 13C NMR titration. It was found that deuteration decreases the pKa by 0.034 ± 0.002. The experimental data are supported by theoretical calculations, which, in turn, allowed to relate the acidity decrease to the lowering of glycine vibrational frequencies upon deuteration.
