✦ Synopsis

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 at an early stage. The strengths and weaknesses of RAS as a probe of surface order are described and attention is drawn to the importance of morphological changes in surface order due to molecular substrate interactions. The applicability of RAS to the metal/liquid interface is described together with recent advances in instrumentation which give RAS the potential to monitor molecular assembly in real time and in a variety of environments.

The use of ab initio quantum chemical methods to aid in the interpretation of resonance Raman spectra is illustrated with examples where the resonant electronic absorption spectra are unstructured. In such cases only the gradient of the excited electronic state potential energy surface at the ground

The "bottom-up" construction of functional structures relies on the sophisticated interplay between individual structural units. [1][2][3] In most cases, the assembly of these building blocks is based on noncovalent interactions that shape extended supramolecular entities in variable dimensions. [4]
