Reflectance anisotropy spectroscopy: A probe to explore organic epitaxial growth [PDF]

, 2009
Reflectance anisotropy spectroscopy (RAS) is demonstrated to be particularly suitable for studying the deposition of organic epitaxial layers in ultrahigh vacuum by organic molecular beam epitaxy, thanks to its high sensitivity and applicability in situ.

The use of reflection anisotropy spectroscopy to assess the alignment of collagen [PDF]

Journal of Physics D: Applied Physics, 2011
The alignment of collagen fibres in tissue has a major influence on their mechanical properties. This study investigated the ability of reflection anisotropy spectroscopy (RAS) to determine the degree of alignment of collagen fibres deposited onto surfaces and secreted by mouse fibroblast cells in vitro.
