Surface Raman Scattering

At an electrode/solution interface, it is possible to obtain all three types of Raman scattering. If a thick surface film is formed by electrode reaction or [Pg.264]

A RRS process can be distinguished from a SERS process by several characteristics. Among these are (1) a RR spectrum can be obtained on a non-SERS-active metal such as Pt or Hg or on a smooth SERS-active metal, while SERS can only be obtained on a roughened SERS-active metal such as Ag, Cu, or Au, (2) a RR spectrum may show strong overtones or combination bands in contrast to a SERS spectrum, which does not show such bands with intensities comparable to those of fundamental modes, and (3) the influence of parallel and perpendicularly polarized light on band intensities may be different in the two light scattering processes (see below). [Pg.265]

SERS is localized to the vicinity of a metal surface means that it is a highly specific surface probe which can be used to study both static and dynamic molecular processes at activated metal surfaces. [Pg.266]

The combination of atomic force microscopy (AFM) and Raman spectroscopy is another approach to attain high spatial resolution. AFM also employs a sharp tip close to a sample surface. When the tip is made of metal and light is irradiated onto the tip and surface, Raman scattering is largely enhanced. In this way, a spatial resolution of 15 nm is achieved [2]. [Pg.4]

Bryant and Pemberton [379, 380] have employed surface Raman scattering to study thiol films on silver and gold and their results confirm the postulated difference in bonding. [Pg.128]

The enhancement of the surface Raman scattering of dyes at their resonance (which may be shifted on the surface as compared to solution) is that of normal Raman scatterers. [Pg.306]

With increasing sensitivity of detectors, the detection of unenhanced surface Raman scattering becomes a possibility, and if this is achieved a wide range of effects can be investigated. In particular the determination of adsorbate orientation from depolarisation ratios and the angular dependence of the Raman signal will be possible. Currently, such measurements only serve as a means of investigating the enhancement mechanism. [Pg.346]
