Abstract

The application of vibrational spectroscopy to the study of inorganic and bioinorganic structures and dynamics has a rich history. Recent advances in vibrational spectroscopic techniques have increased the utility of these methods. Time-resolved methods in particular have benefited from advances in lasers and other enabling technologies. In this chapter we describe the application of both Raman and infrared methods to problems in inorganic chemistry, with a focus on bioinorganic systems. We also describe difference vibrational spectroscopy methods for the analysis of metal active sites within complex protein structures. We develop quantitative rules for the relationships between force constants and bond distances. Such relationships are useful for predicting bond distances for cases where it is difficult to measure them otherwise, such as for excited states of molecules. Finally, we review time-resolved Raman and IR methods and their application to the study of the structures and dynamics of excited states and chemical reactions of inorganic systems.
