{"product_id":"9783642293801","title":"Molecular Conformation and Organic Photochemistry : Time-Resolved Photoionization Studies (Springer Theses)","description":"This outstanding thesis charts the links between a molecule's shape and its photochemical reactivity, which has highly truncated excited states radically different to those in ground-state chemistry. Its novel use of bichromophoric interactions is promising.\u003cbr\u003e Rasmus Brogaard's thesis digs into the fundamental issue of how the shape of a molecules relates to its photochemical reactivity. This relation is drastically different from that of ground-state chemistry, since lifetimes of excited states are often comparable to or even shorter than the time scales of conformational changes. Combining theoretical and experimental efforts in femto-second time-resolved photoionization Rasmus Brogaard finds that a requirement for an efficient photochemical reaction is the prearrangement of the constituents in a reactive conformation. \u003cbr\u003eFurhtermore, he is able to show that by exploiting a strong ionic interaction between two chromophores, a coherent molecular motion can be induced and probed in real-time. This way of using bichromophoric interactions provides a promising strategy for future research on conformational dynamics.
