The principles and applications of laser Raman spectroscopy to the “in situ” determination of the structure and composition of corrosion and inhibitor films on metals in aqueous solution environments are discussed. Results of studies on copper, nickel and iron are presented as illustrative examples. Work on corrosion inhibition by organic compounds and on passivity breakdown on iron by thiocyanate are presented. Extension of the technique to studies in high temperature high pressure aqueous environments and the development of a new difference Raman spectroscopic technique are discussed. The advantages and limitations of the Raman technique are pointed out.
