Attosecond Science is the study of processes that occur on a time scale of a few attoseconds (10-18 seconds) or less. Electrons provide the screening to stabilize molecules, and thus electronic redistribution initiates all chemical changes, including isomerization and dissociation. This means that electron motion is the means by which light energy is harnessed in photochemistry.

In order to know the earliest processes involved in the chemical process, it's only natural to effort to trace the evolution of electrons on their intrinsic timescales. The natural timescale for electron motion in atoms and molecules is about 100 times quicker than the nuclei: electrons shift across a molecular bond in 0.1 to 1 femtosecond.

High Harmonics Generation Spectroscopy: Attosecond science allows the examination of multi-electron dynamics in atoms, molecules, and solids. HHG spectroscopy exploits a built-in pump-probe process: driven by the strong laser field, the liberated electron wave packet returns to the parent ion and probes the hole through radiative recombination. In turn, this results in the emission of higher-order harmonics of the driving laser field. The emitted attosecond burst of light takes a snapshot of the system, probing the evolving wavefunction, in an attosecond movie in which each harmonic order serves as one frame.
