Abstract/OtherAbstract:
|
Secondary deuterium isotope effects (IE) on the acidity (pK(a)) of glycine were measured by ¹³C NMR titration. It was found that deuteration decreases the pK(a) 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. |
