AB  - The thesis presents progress made towards a thorough understanding of the photodissociation and geminate recombination of triiodide anion (I<sub>3</sub><sup>−</sup>) in solution and solid state using novel time-resolved spectroscopic and structural methods that have matured in the past decade. An isolated I<sub>3</sub><sup>−</sup> has only three degrees of freedom, but in the condensed phase, the case of an open quantum system, its chemistry is transformed because other degrees of freedom from the surroundings (the bath) need to be fully taken into account. This system is a textbook example for understanding dissociation and recombination processes in condensed phases, but unresolved issues about the reaction pathways remain. To probe the issues, firstly, mid-UV pulse shaper-based closed-loop adaptive control as well as open-loop power and chirp control schemes were used in conjunction with single-color pump-probe detection of the yield of the photoproduct diiodide (I<sub>2</sub><sup>−·</sup>) to study the above reaction in ethanol solution. The experiments revealed a strong pump-chirp dependence of the I<sub>2</sub><sup>−·</sup>-yield (as much as 40
