Triplet excited states in molecules and materials play an important role in many practical applications, from phosphorescent pigments to photodynamic therapy, and even photovoltaic solar cells. New materials that exhibit triplet state photochemistry are constantly under development, and understanding the lifetime and energy transfer processes of their triplet states is a fundamental step in their design and optimisation. In this application note, we demonstrate how transient absorption spectroscopy and temperature-dependent measurements can be employed to investigate and understand the nature of photoexcited triplet states of a molecule.
