Wavelength-dependent photodissociation of iodomethylbutane [PDF]
Scientific ReportsUltrashort XUV pulses of the Free-Electron-LASer in Hamburg (FLASH) were used to investigate laser-induced fragmentation patterns of the prototypical chiral molecule 1-iodo-2-methyl-butane ( $$\hbox {C}_5$$ $$\hbox {H}_{11}$$ I) in a pump-probe scheme ...

Photodissociation of interstellar ArH+ [PDF]
Astronomy & Astrophysics, 2014 Aims. Following the recent detection of 36ArH+ in the Crab nebula spectrum, we have computed the photodissociation rate of ArH+ in order to constrain the physical processes at work in this environment. Methods.

Acta Physica Sinica, 1988 The population on 6p2 3P2 metastable state and 6p2 3P0 ground state of Pb atoms are de-monstrated, which are originated from dissociating PbCl2 by the fourth harmonic of YAG lasers. The population ratio of 3P2 to 3P0 is measured in terms of laser-induced fluorescence.

Photodissociation dynamics of N3+ [PDF]
The Journal of Chemical Physics, 2022 The photodissociation dynamics of N3+ excited from its (linear) 3Σg−/(bent) 3A″ ground to the first excited singlet and triplet states is investigated. Three-dimensional potential energy surfaces for the 1A′, 1A″, and 3A′ electronic states, correlating with the 1Δg and 3Πu states in linear geometry, for N3+ are constructed using high-level electronic ...
