• Resumen

  • Students in the biophysical chemistry laboratory use 1H NMR to evaluate the equilibrium constant for the cis-trans isomerism of N-acetyl-L-proline. The four solvent systems (45:55 d6-benzene-CDCl3, d6-acetone, D2O with pH < 2, and D2O with pH > 7) demonstrate the effects of solvent polarity and aqueous pH.
