Rasmus Brogaard's thesis digs into the elemental factor of ways the form of a molecule pertains to its photochemical reactivity. This relation is enormously diversified from that of ground-state chemistry, on the grounds that lifetimes of excited states are usually equivalent to or maybe shorter than the time scales of conformational adjustments. Combining theoretical and experimental efforts in femto-second time-resolved photoionization Rasmus Brogaard reveals requirement for a good photochemical response is the prearrangement of the elements in a reactive conformation.
Furthermore, he's capable of exhibit that via exploiting a powerful ionic interplay among chromophores, a coherent molecular movement will be triggered and probed in real-time. this manner of utilizing bichromophoric interactions presents a promising approach for destiny examine on conformational dynamics.

Because of this resemblance, the photoelectron spectra of Rydberg states are sharp peaks, due to a narrow Franck–Condon envelope favoring v = 0 transitions (Ref.  and references therein). Thus, Gosselin et al. demonstrated how IC between two Rydberg states exhibiting corresponding ionization correlations was easily followed in the time-resolved photoelectron spectrum due to clearly distinguishable spectra of the states . The above was largely focused on the general case of IC between electronic states, but before ending this section it is worth elaborating slightly on how nuclear dynamics can be probed.

Thus, the pioneering theoretical work of Seel and Domcke lead to the birth of ultrafast time-resolved photoionization experiments [1, 2].
