S. Schneider et al., KINETIC EFFECTS IN SURFACE-ENHANCED RAMAN-SPECTROSCOPY - DOES IT HAVEPOTENTIAL AS AN ANALYTICAL TOOL, Analyst, 118(6), 1993, pp. 689-694
The intensity of surface-enhanced Raman spectra, in general, and the r
elative intensities of different bands, in particular, depend on many
parameters and are usually subject to variation with respect to standi
ng time. Previously, several attempts have been made to explain the ph
ysical background to some of these variations, but so far no generally
valid explanation has been proposed. As a consequence, surface-enhanc
ed Raman spectroscopy, despite its extremely high sensitivity, has not
yet been accepted as an analytical tool. The work described in this p
aper demonstrates that an analytical application is possible under cer
tain conditions.
