RAIRS of phenyl thiols on gold The RAIRS spectra of the series of phenyl thiols all exhibit intense peaks at 1267, and 1590 cm−1, see Fig. 2. These peaks correspond to the in-plane stretching modes of the benzene ring, and their net dipole vector change is parallel to the molecular axis. Based on surface selection rules, these in-plane ...
