“…This model is supported by theoretical calculations of the overlap of the initially excited Rydberg states and final states of the shake up process. Using fluorescence spectroscopy, a similar behaviour of this "spectator dissociation" of Rydberg excitations was observed for innershell excitations of other molecules before [16][17][18]. Our results corroborate the suggested model and should stimulate further theoretical effort to determine quantitative production cross sections of excited fragments after core excitation of the water molecule.…”

We report Lyman series emission cross sections of neutral hydrogen dissociation fragments after valence (15-34 eV) and inner-shell (533-542 eV) excitation of water vapor with monochromatic synchrotron radiation as functions of the exciting-photon energy. In the valence excitation energy region the thermodynamical limits of the production of the differently excited hydrogen fragments is directly observed and absolute emission cross sections were determined. For resonant innershell excitations, the fluorescing excited hydrogen state is found to be strongly dependent on the molecular or Rydberg-like character of the excitation.

“…Being site and state selective [18][19][20][21][22][23][24][25][26], dispersed fluorescence provides extensive information on the emitter and on the initial and final states of the emission process. These advantages are routinely utilized in, e.g., astrophysics to characterize emission lines in small system [37].…”

“…Measurements of emitted photons provide information about the emitter (site selectivity), its transition initial and final states (state selectivity), and on the lifetime of the emission process (time resolution). The photon-induced fluorescence spectroscopy [18] (PIFS) has been successfully used for the quantitative investigation of photoionization, Auger-, and autoionization processes in molecules [19][20][21][22][23][24][25][26] with particular sensitivity to processes with low-energy electron emission [19][20][21]. Despite the advantages mentioned above, fluorescence subsequent to ICD processes has not yet been recorded, as the target density in the necessary cluster experiments was very low.…”

Detecting ultrafast interatomic electronic processes in media by fluorescence

et al. 2014

View full text Add to dashboard Cite

Interatomic coulombic decay (ICD), a radiationless transition in weakly bonded systems, such as solutes or van der Waals bound aggregates, is an effective source for electrons of low kinetic energy. So far, the ICD processes could only be probed in ultra-high vacuum by using electron and/or ion spectroscopy. Here we show that resonant ICD processes can also be detected by measuring the subsequently emitted characteristic fluorescence radiation, which makes their study in dense media possible.

Fluorescence cascades evoked by resonant interatomic Coulombic decay of inner-valence excited neon clusters

et al. 2017

View full text Add to dashboard Cite

Resonant interatomic Coulombic decay (RICD) in inner-valence excited neon clusters is observed by a combination of vacuumultraviolet (VUV) and UV/visible fluorescence spectroscopy. These ultrafast interatomic electronic processes efficiently quench radiation emission from inner-valence excited clusters. After RICD took place, outer-valence excited clusters relax further by emission of fluorescence. The direct correspondence of the structures observed in the VUV and UV/visible fluorescence signals implies that the final states of the spectator RICD decay by a cascade of radiative decays: First, by the Rydberg-to-Rydberg transitions in the UV/visible spectral range, and then, by the Rydberg-to-valence transition in the VUV range. Our study demonstrates a possibility of detecting interatomic electronic processes by UV/visible fluorescence spectroscopy.
