✦ Synopsis

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. Recently, we have shown that RAS can be successfully used to study the optical anisotropies of organic Langmuir-Blodgett films. In this paper we have extended our study to thick Langmuir-Blodgett films of porphyrins, a class of molecules widely studied for the importance of their physico-chemical properties.
