Structural dynamics in semi-quantum and quantum solids (Ne, H2 and D2) is reported, and compared to results in classical solids such as Ar. The structural dynamics is driven by excitation of the lowest Rydberg state of the NO impurity. The resulting charge ...
The dynamics of non-polar electronic solvation has been studied on a model system consisting of NO-doped solid Ar. Excitation of the lowest Rydberg state A(3ss) of NO leads to formation of an electronic 'bubble', which has been studied by femtosecond pump- ...
Rydberg-Rydberg transitions are induced by absorption from the lowest Rydberg state of NO A 2S+ (3ss) in Ar matrixes, which is excited by an ArF laser at 193.3 nm. The depopulation of the A(v = 0) level to higher Rydberg states is probed by depletion of it ...
Transitions from bound atomic Rydberg Stark states in a static electric field to autoionizing Rydberg states above the electric-field-induced ionization threshold are studied using a broadband, tunable free-electron laser (photon energy 160-1400 cm(-1), pu ...
The ultrafast dynamics are reported of bubble formation following excitation of the A 2S+ 3ss(v = 0) Rydberg state of NO trapped in Ar matrixes. The study is carried out by a fs pump-probe technique. The detected signal is the depletion of Rydberg fluoresc ...
The ultrafast dynamics of electronic bubble formation upon excitation of the A(3ss) Rydberg state of NO trapped in solid H2 and D2 was studied by femtosecond pump-probe spectroscopy. The evolution of the spherical bubble is followed in real time by a probe ...
Higher Rydberg states of NO trapped in rare gas matrixes were studied by inducing Rydberg-Rydberg transitions from the lowest A2S+ (3ss) Rydberg state and detecting its fluorescence depletion. This technique unravels Rydberg states, which cannot be accesse ...
An atomic streak camera has been constructed that operates from the near to the far infrared. The photocathode used in conventional streak cameras for the conversion of photons to electrons has been replaced by gas-phase atoms in a Rydberg state. The low b ...
Exptl. evidence is presented for the process of MO Rydbergization postulated by Mulliken, whereby an antibonding orbital continuously changes its character from predominantly Rydberg to predominantly valence on its way to dissocn. By matrix-isolation spect ...
Environmental effects on electronic states of small mols. in solid rare gases and in liqs. have severe consequences on the photochem.; examples for valence, Rydberg and ionic states as well as the connection to photochem. dry etching are treated. The repul ...
