The studies of defects formed by impurity particles (atoms, molecules, exciplexes, clusters,
free electrons, and positive ions) embedded in liquid and solid 4He are reviewed. The …

We perform time resolved pump–probe spectroscopy on small halogen molecules ClF, Cl2,
Br2, and I2 embedded in rare gas solids (RGS). We find that dissociation, angular …

We present the results of an ab initio study of the interaction of electronically excited NO (A Σ
2+) with rare gas (Rg) atoms. The bound states of each NO (A)–Rg species are determined …

A coherent zone boundary phonon (ZBP) of solid Kr (fm= 1.54 TH z) is observed in ultrafast
pump-probe spectra of I 2 guest molecules in a Kr crystal. Its phase is stable for at least 10 …

Molecular dynamics simulations and both normal mode and hyperspherical mode analyses
of NO-doped Kr solid are carried out in order to get insights into the structural relaxation of …

Pump–probe measurements of I2 in solid Ar are reported and analyzed to extract a
description of cage response to impulsive excitation, from the gentle kick, up to the breaking …

The dynamics of electronbubble'formation upon excitation of the A (3sσ) Rydberg orbital of
NO in solid Ne was investigated by means of femtosecond pump–probe spectroscopy. We …

Molecular-dynamics simulations of structural relaxation in electronically excited NO-doped
solid neon are presented. The NO impurity is excited to its lowest A (3 s σ) Rydberg state …

The intermolecular potential of the first Rydberg state of the NO–Ne system has been
calculated using highly accurate ab initio calculations. The interaction is repulsive with …

Photoexcitation of NO embedded in rare gas matrices triggers a shock-wave like radial
perturbation of the surrounding rare gas atoms. In this Letter, we present quantum dynamical …
