Ziegler et al.

Since the HRS scattering cross section is so small, enhancement of the signal intensity is indispensable for a practical use of the HRS technique in the field of molecular science. As already mentioned, one of the methods for signal enhancement is to use plasmonic resonances of metal nanostructures [20, 21, 25]. This enhancement technique is called surface-enhanced hyper-Raman scattering (SEHRS) because it is similar to that of surface-enhanced Raman scattering (SERS). In SERS or SEHRS, both excitation absorption and scattered emission benefit from plasmonic field enhancement. Therefore, the plasmonic enhancement factor M is described as... [Pg.105]

Instrumentation. Instmmentation in the reported investigations is similar to that employed in SERS [497]. A powerful laser system is employed. In a study of pyrazine and pyridine adsorbed on a roughened silver electrode, it was observed, that spectra measured with adsorbed centrosymmetric pyrazine showed additional bands that were not observed with SERS [497]. With the non-centrosymmetric pyridine, the SEHR spectra were very similar to the respective SER spectra no new bands were found. Surface enhanced hyper-Raman spectra were found to be more sensitive (than SERS) towards interaction between the adsorbate and the surface. This is illustrated in vibrational spectra of bis(4-pyridine)acetylene (BPA) adsorbed on a silver electrode [497]. [Pg.123]
