Abstract
Vibrational (infrared) spectroscopy is often referred to as molecular spectroscopy to emphasize that it is the source of much of the known molecular-structure data, e.g., molecular symmetry, bond lengths, and bond angles [1]. Coupled with statistical mechanics, vibrational spectroscopy can also allow the calculation of thermodynamic properties [2]. Of course, catalysis is by definition a kinetic phenomena, and therefore it is noteworthy that vibrational spectroscopy has also been used to follow the transient response of kinetically significant (as opposed to stable, unreactive) intermediates on heterogeneous catalysts [3–5].
