Molecules, Minerals, & Metals: A Story of Resonance Revealed by Raman Spectroscopy

Document Type


Publication Date



Raman spectroscopy is a technique that measures the vibrational properties of a molecular or crystal structure. In this lecture he will present examples of the use of Raman to identify gemstones, minerals, and molecules under ambient conditions. Applications are found in medicine, biology, geology, chemistry, physics, engineering, forensic science, and in any discipline where there is a need for the non-destructive study of Raman-active materials. In well behaved systems, sub-monolayer levels of material (fewer than 500 mole-cules) can be observed using Surface-Enhanced Raman Scattering (SERS) techniques.

Greg Hope is a Professor of Physical Chemistry in the School of Natural Sciences at Griffith University in Brisbane, Australia. He has published 170 refereed papers and 37 commissioned research reports, predominantly for Australian industry. He has made extensive use of SERS techniques to investigate the monolayer and sub-monolayer interaction of solution species with metal-enhanced surfaces of metals and minerals.
