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

Routes of odd-even harmonic emission from oriented polar molecules.
TL;DR: The comparison between the HHG yields of all routes versus one certain route demonstrates that the routes in which the electron ionizes from the gerade component of the asymmetric orbital contribute mainly to odd-even HHG.

Monitoring long-term evolution of molecular vibrational wave packet using high-order harmonic generation
TL;DR: In this article, a method for probing ultrafast nuclear dynamics in molecules using transient enhancement of high-order harmonic generation (HHG) was proposed, which exploits strong dependence of the overall harmonic yield in a fixed spectral range on the nuclear separation in a molecule, which is shown to take place for both aligned and randomly oriented molecules.

Control of recollision wave packets for molecular orbital tomography using short laser pulses
TL;DR: In this paper, the authors show that extremely short phase-stabilized laser pulses offer control over the momentum distribution of the returning electrons, and the signatures of the semi-classical distributions are observed in harmonic spectra obtained by the numerical solution of the time-dependent Schrodinger equation.

Time and momentum distributions of rescattering electrons
TL;DR: In this article, the authors define rescattering electron momentum distributions within the framework of the time-dependent Schrodinger equation without making the strong field approximation, and investigate the dependence of momentum distributions on molecular orientation, orbital symmetry and correlation.
