Recent advances in the study of quantum vibrations and rotations in the fundamental
hydrogen molecules are reported. Using the deuterium molecules (D2+ and D2) as …

Given their importance, hydrogen bonds (H-bonds) have been the subject of intense
investigation since their discovery. Indeed, H-bonds play a fundamental role in determining …

In semiconductors, photo-excited charge carriers exist as a gas of electrons and holes,
bound electron–hole pairs (excitons), biexcitons and trions,,–. At sufficiently high densities …

We study high-energy angle-resolved photoelectron spectra of molecules in strong fields. In
an oscillating laser electric field, electrons released earlier in the pulse may return to …

An ab initio theoretical framework for the simulation of femtosecond time-resolved transient
absorption (TA) pump–probe (PP) spectra with quasi-classical trajectories is presented. The …

Upon photoexcitation, molecules can undergo numerous complex processes, such as
isomerization and roaming, leading to changes in the molecular and electronic structure …

The nucleobase uracil exhibits high photostability due to ultrafast relaxation processes
mediated by conical intersections (CoIns), where the interplay between nuclear and electron …

The energy conversion efficiency of organic solar cells seems crucial for a clean future. The
design of new light-harvesting devices needs an in-depth understanding of their optical …

Phase-modulated wave packet interferometry is combined with mass-resolved photoion
detection to investigate rubidium atoms attached to helium nanodroplets in a molecular …

This study utilized the laser “pump–probe” technique to investigate the properties of a
rhodamine 6G laser dye. A 532-nm wavelength laser was employed for excitation of the dye …
