The polyelectrolyte-tethered bilayers were investigated by means of time dependent surface plasmon spectroscopy, impedance spectroscopy, FRAP, as well as NR [27], The NR data given in Fig. 12 were first calculated based on a model that included the substrate and a box for the polyelectrolyte multilayer (A), and an additional box for the lipid bilayer (C). However, in order to fit the experimental NR curve, a top layer had to be added that was approximated by a uniform coating with average scattering length density b/V shown in the inset of Fig. 12. The thickness of...

The method is sometimes called surface plasmon spectroscopy (SPS) the term resonance refers to the peculiarities of the reflectivity vs. angle of incidence plots obtained with the method (minimum of reflectivity). 

The techniques already discussed account for the vast majority of in situ spectro-electrochemical studies. There are, however, a few others, namely, surface conductance, in situ photoemission, photocurrent spectroscopy, in situ mass spectrometry, surface plasmon spectroscopy, Mossbauer spectroscopy, and in situ X-ray diffraction that at least deserve to be mentioned. 

However, in contrast to simple reflection measurements or by surface plasmon spectroscopy at one angle or wavelength [153], spectral meas-... 

X-ray photoelectron spectroscopy (XPS) indicated that the oxygen-rich cavity resides at the outer interface and that the sulfur atoms are located near the gold surface. The thickness of the monolayers, measured by surface plasmon spectroscopy is 22( 2) A for 8a and 8c, and 24( 2) A for 8b, which is in accordance with the expected values. Electrochemical measurements show that the heterogenous electron transfer between a gold electrode covered with a monolayer of 8a and a 1 mM 0.1 M K2SO4... 

Merocyanines are widely used as solvatochromic dyes. Fujita et al. demonstrated that the Brooker s dye analogue (Fig. 32, 24) shows a colour change based on protonation and deprotonation in a densely packed SAM (Fig. 32, 24) [196]. Surface plasmon spectroscopy and X-ray photoelectron spectroscopy indicate that the monolayers are closely packed. The layer thickness is consistent with the molecules having a tUt angle of 30° to the surface normal IRRAS spectroscopy shows that the chromophores are located in a polar local dielectric situation even in non-polar solvents. Nonetheless, the deprotonated, zwitterionic form of the dye shows a distinct negative solva-tochromism depending on the solvent polarity. 

Surface plasmon resonance spectroscopy (SPR) has become a widely accepted optical technique for the characterization of interfaces and thin films. The underlying physical principles have been worked out and are summarized in great detail in the literature. With the availability of commercial instruments applications of surface plasmon spectroscopies have been reported in many diverse fields of science and engineering.
