Rasmus Brogaard's thesis digs into the fundamental issue of how the
shape of a molecule 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.
Rasmus Brogaard's thesis digs into the fundamental issue of how the shape of a molecule 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. Furthermore, 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.
