Figure 2: Infrared spectra of 2-phenylethylthiol and of gold cluster.
From: Chirality transfer from gold nanocluster to adsorbate evidenced by vibrational circular dichroism
Infrared spectra of 2-phenylethylthiol (b) and Au38(2-PET)24 cluster (a). The experimental spectra are shown in black. Calculated spectra are also shown (red and blue). Red (blue) spectra are associated with 2-PET and 2-phenylethylthiol, respectively, adopting gauche (anti) conformation. For the calculation of the top spectra a Au4(2-PET)4 cyclic structure was used as a model for the staple motifs found on the Au38(2-PET)24 cluster. For the red (blue) spectrum all the 2-PET molecules within the Au4(2-PET)4 structure adopt gauche (anti) conformation. Green dotted lines mark wagging modes that are sensitive to conformation.
