TLDR
In this article, high-order harmonic generation for molecules in linearly polarized laser pulses by numerical solution of the Schr\"odinger equation was studied and maxima and minima due to intramolecular interference were found in the dependence of the harmonic intensities on the internuclear distance and on the orientation of the molecules.Abstract:
We study high-order harmonic generation for ${\mathrm{H}}_{2}^{+}$ and ${\mathrm{H}}_{2}$ model molecules in linearly polarized laser pulses by numerical solution of the Schr\"odinger equation. Maxima and minima due to intramolecular interference are found in the dependence of the harmonic intensities on the internuclear distance and on the orientation of the molecules. These extrema can be approximately predicted by regarding them as the result of interference between two radiating point sources located at the positions of the nuclei.read more

Molecular reactivity dynamics in a confined environment
TL;DR: Time evolution of various reactivity parameters viz. hardness, electrophilicity, chemical potential, polarizability, etc. in a confined environment has been studied through quantum fluid density functional theory formalism during time dependent processes such as proton-molecule collisions and molecule-field interaction.

Theoretical study of attosecond dynamics in atoms and molecules using high-order harmonic generation as a self-probe
TL;DR: In this article, the authors used high-order harmonic generation (HHG) as a self-probe process to examine electronic and nuclear dynamics on the attosecond scale with Angstrom resolution, insisting on the spectral phase.

High-order harmonic generation in vibrating molecules
C. C. Chirila,Manfred Lein +1 more
TL;DR: In this article, the Schrodinger equation for a model H2 molecule is interpreted by analysing the influence of the vibrational motion in the framework of the strong-field approximation, and it is shown that more intense harmonics are generated in heavier isotopes due to the slower nuclear motion.
