In order to make meaningful physical measurements on monolayer and multilayer L-B films, it is essential that the films be characterized to determine the molecular structure, unformity of the film and layer-to-layer structural correlation. To probe the molecular structure, our research group has utilized a variety of spectroscopic techniques such as u.v.-visible spectroscopy, ATR-IR, wave-guide Raman, surface-plasmon wave Raman spectroscopy and inelastic electron tunneling. The spectroscopic techniques... 

The quality, perfection, and stability of the layered assemblies and details of their internal architecture can be analyzed by a combination of different methods such as X-ray diffraction, spectroscopic (IR, UV/Vis, Raman) techniques, wave-guide spectroscopy and so on [74]. As an example. Figure 9.5 shows the small-angle X-ray diffraction pattern obtained at a grazing incident from an assembly of 28 copoly(glutamate) layers on a silicon wafer [82,83]. The insert represents a molecular picture of the assembly with only two of the 28 layers drawn.
