Enantiodiscrimination between an N-Acetyl-L-cysteine SAM and Proline : An In Situ Spectroscopic and Computational Study

Bieri, Marco ; Bürgi, Thomas

In: ChemPhysChem, 2006, vol. 7, p. 514-523

A combination of attenuated total reflection infrared (ATR-IR) and modulation excitation spectroscopy (MES) is used to study the enantiodiscriminating interactions between proline and a chiral, self-assembled monolayer (SAM) of N-acetyl-L-cysteine on gold. The N-acetyl-L-cysteine SAM consists of a mixture of protonated and deprotonated molecules. Whereas both species are influenced...
