Experimental Coherent Laser Control of Physicochemical Processes

Chemical dynamics, molecular energetics, and kinetics at the synchrotron

“…In reaction dynamics it can involve basic kinetics or energetics, 2 or it can represent the most elegant experiments in state-resolved 3 and angular details, 4 even coherence effects. 5 It can be science performed with the shortest pulses in the world, in the attosecond time domain. 6 More broadly, chemical dynamics involves complex processes, such as combustion and heterogeneous chemistry, 7 with concurrent impacts on atmospheric chemistry, radiative forcing, and global warming.…”

A Stark Future for Quantum Control

“…8,63,64 This approach exploits the large coherent bandwidth and very high field intensities intrinsic to such pulses and has been successfully demonstrated in the fragmentation-ionization of polyatomic molecules. 9,10 One challenge with the strong field approach is that numerous, simultaneously occurring processes are potentially responsible for contributing to the observed final outcome. 5 These potentially include high-order multiphoton ionization, enhanced ionization, 65,66 nonadiabatic multielectron ionization, 67 and Coulomb explosion, 68 multiphoton resonances leading to propagation on multiple potential energy surfaces, dynamic Stark effects, adiabatic passage by light-induced potentials, [69][70][71] and bond hardening/softening.…”

Electronic structure in real time: mapping valence electron rearrangements during chemical reactions

“…Since these original studies, the field of femtochemistry has rapidly evolved and it is not the aim of this perspective to review this development. Rather, the reader is referred to a number of excellent articles, reviews and books that have appeared over the years (3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15).…”
