Abstract

Modern surface science is now emerging into a regime in which understanding the relationship betweeen structure and function will occupy an ever more prominent role. To this end one important piece of information concerns the three dimensional orientation of complex adsorbates at an interface. We have been using total internal reflection excited surface Raman scattering and waveguide mediated linear dichroism to measure the tilt angles of molecules adsorbed under realistic conditions (i.e. at the solid-liquid interface). These efforts will be described and compared.
