TL;DR: Attosecond pump–probe strategies are established as a powerful tool for investigating the complex molecular dynamics that result from the coupling between electronic and nuclear motions beyond the usual Born–Oppenheimer approximation.

TL;DR: An interferometric pump-probe technique that uses a free WP as a reference to measure a bound WP and analysis of the interferogram allows us to determine the bound WP components with a spectral resolution much better than the inverse of the AP duration.

TL;DR: In experiments where hydrogen molecules were dissociatively ionized by an attosecond pulse train in the presence of a near-infrared field, the ionization probability is sensitive to the instantaneous polarization of the molecule by the IR electric field and this work demonstrates that it has probed the IR-induced electron dynamics withAttosecond pulses.

TL;DR: A pronounced dependence of the H;{+} kinetic energy distribution on XUV-IR delay is observed that can be explained in terms of the adiabatic propagation of theH_{2};{-} wave packet on field-dressed potential energy curves.

TL;DR: In this article, the authors demonstrate that dissociative ionization of O2 can be controlled by the relative delay between an attosecond pulse train (APT) and a copropagating infrared (IR) field.
