Ultrafast dynamics through conical intersections and intramolecular vibrational energy redistribution in styrene

“…This assumption, together with the electronic correlations described above and summarized in table 2, allows approximate photoelectron band energies to be predicted between excited states, and thus the TRPES bands can be assigned to first order, as illustrated in figure 1. Such an approximate assignment method has been reported in the literature as an analysis tool for time-resolved photoionisation studies of styrene and other molecules 18,24,29 and provides theoretical band energies that agree well with those observed.…”

Competing ultrafast intersystem crossing and internal conversion in the “channel 3” region of benzene

“…TRPES has been employed to monitor wave packet dynamics in simple diatomic molecules, 36 to follow IC in polyenes, 37 photodissociation, [38][39][40] intramolecular vibrational energy redistribution (IVR) 41 and ISC. 40,42 However, when there is a high density of electronically excited states correlating to the same electronic state of the cation, sometimes referred to as a type II Koopman correlation, it can be extremely challenging to decompose the evolving wavefunction into its constituent parts.…”

Colloquium: Aligning molecules with strong laser pulses

“…In recent years much effort has been devoted to the application of time-domain methods to probe the dynamics of nonradiative transitions (Seel and Domcke, 1991;Kim, Schick, and Weber, 1995;Radloff et al, 1997;Blanchet et al, 1999). Here, one is predominantly interested in internal conversions, which are often ultrafast and difficult to study in the energy domain.…”
