Because the optical properties of very small particles are frequently dominated by almost-unavoidable clustering of particles, this work has attempted to study the spectroscopy of systems of particles growing from one atom through multi-atom clusters to small particles. The techniques used are 1 low temperature matrix isolation spectroscopy in solid argon, and 2 in situ study of metal particles produced and growing in an inert gas. In order to help clarify the issue regarding the size regime at which bulk optical properties cease to be a valid approximation for increasingly small particles, Part I surveys this question, based both on the present results and on the work of many authors published in the open literature. Part II gives more specific details on the matrix isolation and gas phase spectroscopy.
