Transient Absorption Spectroscopy in Inorganic Systems

Transient absorption spectroscopy is one the most popular methods to study photochemistry and photophysics. This technique allows observation of dynamics in electronic excited states after photoexcitation over a wide range timescales, from femtosecond millisecond timescales. The probed relaxation involve multiple channels competition, such as internal conversion, intersystem crossing, fluorescence, energy transfer, electron proton-coupled chemical reactions. aim this chapter provide general background discuss state-of-the-art experimental techniques for transient measurements. will be illustrated by recent applications photoinduced processes inorganic systems including molecular hybrid systems, particular toward renewable applications. Desirable developments, no means exhaustive, then discussed sustain future research.
