Understanding photogenerated excited electronic states, light mediated chemical reactions and intermediates, and photo-driven energy or electron transfers is paramount to designing and developing the next generation of materials from therapeutics to solar cells. Having the ability to measure these processes in the solid state (powder, film, glass) further enables researchers to glean vital photoinduced electronic properties of their materials and devices in their real-world application uses. The Edinburgh Instruments LP980 Transient Absorption Spectrometer, equipped with the diffuse reflection accessory, is used here to measure benzil powder.
