FTIR-Reflectance experiments have proved to be a powerful tool for the determination of molecular orientation in thin films adsorbed onto highly reflecting metals. We propose an original method for determination of the persistence length of molecular orientation in the film. This approach is based o

β¦ Synopsis
We show that reflection anisotropy spectroscopy (RAS) can be used to characterize the growth of organic epilayers on metallic surfaces. Two prototype adsorption systems are studied; one showing the use of RAS in determining molecular orientation, and a second to demonstrate real-time sensitivity to the interface chemistry during adsorption.

The potential of the optical technique of Reflection Anisotropy Spectroscopy (RAS) as a probe of molecular assembly on metal surfaces is described. It is shown that RAS can be used to monitor the growth of molecular layers on both disordered and ordered substrates though work in the later regime is
Until now, with a few exceptions, Reflectance Anisotropy Spectroscopy (RAS) has been applied mostly to inorganic semiconductors and metals, proving to be a powerful tool to investigate their optical properties, via anisotropies introduced by the surface in otherwise isotropic bulk materials. Recentl
