Femtosecond wave-packet revivals in ozone

Time-resolved photoelectron spectroscopy: the continuing evolution of a mature technique

“…[42][43][44] In a number of cases, a significant effort has been expended to obtain a crosscorrelation shorter than 32 fs. 40,[45][46][47] An intense EUV source as a seeded FEL as FERMI has also been used as a probe pulse. 48,49 Even shorter time-resolution has been achieved in several of investigations on ultrafast charge-migration triggered by photoionization.…”

Quantum coherence in molecular photoionization

“…In very small molecules, where the vibrational motion remains low-dimensional, periodic revivals of the cross-correlation function C ba , and therefore the electronic wavepacket motion, can be expected to persist for many vibrational periods 53,54 . A similar situation can be expected when the electronic wavepacket evolves on electronic surfaces which are nested either due to the symmetry reasons, or accidentally.…”

Attochemistry: Is Controlling Electrons the Future of Photochemistry?

“…In particular, a 2019 combined theoretical and experimental work investigated the dynamics induced upon population of an electronic wavepacket made of the electronic ground state and the first excited state of neutral O 3 molecule using a deep UV pulse. 67 By modifying the attosecond pulses used for excitation, the initial electronic superposition formed could often be tuned. 33,[68][69][70][71] Historically, at the same time as the first attosecond pulses were generated, the observations by Weinkauf et al served as the catalyst for the development by Cederbaum et al of their charge migration theory, 32,72 whereupon electron correlation drives ultrafast rearrangement of the electron cloud on an attosecond timescale.…”

“…Controlling bound electrons without ionization using attosecond pulses is certainly challenging, because the pulses required are harder to generate being few-cycle or less; however, the generation of half-cycle attosecond pulses in the UV–vis range, and few-cycle deep UV sub-2 fs pulses, have been reported. In particular, a 2019 combined theoretical and experimental work investigated the dynamics induced upon population of an electronic wavepacket made of the electronic ground state and the first excited state of neutral O 3 molecule using a deep UV pulse .
