A formidable contender to X-ray diffraction is ultrafast electron crystallography. Whereas the former is more suited to investigate the bulk of the substrate, the time, length, and sensitivity scales of electron crystallography provide powerful and c

We report direct determination of the structures and dynamics of interfacial water on a hydrophilic surface with atomic-scale resolution using ultrafast electron crystallography. On the nanometer scale, we observed the coexistence of ordered surface

The dynamics of electron `bubble' formation upon excitation of the A(3sσ) Rydberg orbital of NO in solid Ne was investigated by means of femtosecond pump–probe spectroscopy. We observe an ultrafast expansion of the bubble, followed by a vibrationa

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

A model based on fluid dynamics is proposed, which describes the dynamics of a photoinduced spherical deformation in solid hydrogen. The dynamics is driven by femtosecond excitation of the lowest A(3ss) Rydberg state of NO trapped in an H2 crystal, l

Fluorescence depletion spectra of the A 2 Σ + (3 sσ ) Rydberg fluorescence of NO in rare-gas and hydrogen matrices are reported in the 0.9–1.3 eV region. Bands due to the Rydberg–Rydberg A 2 Σ + (3 sσ ) –C 2 Π (3 pπ ) and A 2 Σ + (3 sσ

We report on fluorescence lifetime lengthenings of molecular Rydberg states in condensed media in the case of the NO molecule trapped in inert gas matrices. In rare gas matrices, the fluorescence of the A 2Σ+ state originates from two types of sites

Femtosecond transition state spectroscopy of solids: electronic ‘bubble’ formation in solid hydrogen
Publikováno v:
Chemical Physics Letters. 279:65-72
We report the femtosecond nuclear dynamics of an electronic ‘bubble’ in solid H2. The bubble formation results from the impulsive excitation of the lowest Rydberg state A2Σ+ (3sσ) of the NO impurity by a UV femtosecond pulse. The evolution of t

Fluorescence, excitation and fluorescence depletion spectra of the lowest Rydberg states of NO trapped in H2 matrices are reported. The absorption bands are shifted by about 0.58 eV to the blue of the gas phase energy. They are strongly broadened and

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
