abstract = {Ultrashort 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 (C$_5$H$_{11}$I) in a pump-probe
scheme. Ion velocity-map images and mass spectra of
optical-laser-induced fragmentation were obtained for
subsequent FEL exposure with photon energies of 63 eV and 75
eV. These energies specifically address the iodine 4d edge
of neutral and singly charged iodine, respectively. The
presented ion spectra for two optical pump-laser
wavelengths, i.e., 800 nm and 267 nm, reveal substantially
different cationic fragment yields in dependence on the
wavelength and intensity. For the case of 800-nm-initiated
fragmentation, the molecule dissociates notably slower than
for the 267-nm pump. The results underscore the importance
of considering optical-laser wavelength and intensity in the
dissociation dynamics of this prototypical chiral molecule
that is a promising candidate for future studies of its
asymmetric nature.},
