Ahmed Zewail will forever be remembered for three main reasons: first, he was the individual who first demonstrated that the structure and dynamics of atoms in the transition state of chemical reactions could be determined through the judicious use of ultrafast lasers, in a field that he pioneered, for which he coined, called femtochemistry; second, he transformed both gas phase electron diffraction and transmission electron microscopy by improving their temporal resolution some 10 orders of…

TLDR
I knew Zewail as one of his mentors and close friends, and he always used me as a sounding board during the successful rise of his academic career.

TLDR
The evolutionary and revolutionary developments of microscopic imaging are overviewed with a perspective on origins, with the aim of understanding emergent phenomena in complex systems.
Picosecond photofragment spectroscopy. IV. Dynamics of consecutive bond breakage in the reaction C2F4I2→C2F4+ 2I
Picosecond photofragment spectroscopy of the ultraviolet (UV)photodissociation of 1,2‐diiodotetrafluoroethane reveals consecutive breaking of the two C–I bonds. Spin–orbit excited (I^*) atoms show a
Coherence in electronically excited dimers. II. Theory and its relationship to exciton dynamics
A theory of microwave absorption in coherent or incoherent states of multidimensional crystals is developed. Application of the theory to the cluster states (dimer, trimer, tetramer,..., etc) of
Femtosecond Clocking of the Chemical Bond
TLDR
The time required to break the chemical bond in an elementary reaction has been measured and the characteristic repulsion length for the potential governing fragment has been obtained.
Femtosecond Photofragment Spectroscopy: The Reaction ICN → CN + I
In this Letter we report our first results on femtosecond photofragment spectroscopy. The reaction studied is I-CN → [I···CN] → I + CN. A photolysis-and-probe scheme is used to measure the rate of
Real‐time picosecond clocking of the collision complex in a bimolecular reaction: The birth of OH from H+CO2
Picosecond (and femtosecond) photofragment spectroscopy has recently provided time-resolved, state-to-state dynamics of molecular photofragmentation. The focus of these experiments was on
Optical molecular dephasing: principles of and probings by coherent laser spectroscopy
Coherent laser spectroscopy of large molecules is a new and challenging area of study. The strength of this type of optical spectroscopy is that it can probe important dynamical molecular processes
