What Information Can Be Derived from UV-Vis Spectra?
UV-Vis spectra provide a wealth of information that is critical for understanding catalytic processes:
Absorption Peaks: The position and intensity of peaks indicate the presence of specific electronic transitions, which can be correlated to the oxidation state and coordination environment of metal centers in catalysts. Band Gap: The energy difference between the highest occupied molecular orbital (HOMO) and the lowest unoccupied molecular orbital (LUMO) can be inferred, which is crucial for semiconductor catalysts. Charge Transfer: Peaks associated with charge transfer transitions provide insights into the interaction between the catalyst and substrates.
