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.}, keywords = {Chemical Physics (physics.chem-ph) (Other) / Atomic Physics (physics.atom-ph) (Other) / FOS: Physical sciences (Other)}, cin = {FS-FLASH-D / $XFEL_E2_SQS$ / CFEL-XAC / FS-FL / FS-FLASH / FS-FLASH-O / FS-LA / CFEL-DESYT / FS-CFEL-3}, ddc = {600}, cid = {I:(DE-H253)FS-FLASH-D-20160930 / $I:(DE-H253)XFEL_E2_SQS-20210408$ / I:(DE-H253)CFEL-XAC-20240710 / I:(DE-H253)FS-FL-20120731 / I:(DE-H253)FS-FLASH-20140814 / I:(DE-H253)FS-FLASH-O-20160930 / I:(DE-H253)FS-LA-20130416 / I:(DE-H253)CFEL-DESYT-20160930 / I:(DE-H253)FS-CFEL-3-20120731}, pnm = {631 - Matter – Dynamics, Mechanisms and Control (POF4-631) / 6G2 - FLASH (DESY) (POF4-6G2) / DFG project G:(GEPRIS)328961117 - SFB 1319: Extremes Licht zur Analyse und Kontrolle molekularer Chiralität (ELCH) (328961117) / AIM, DFG project G:(GEPRIS)390715994 - EXC 2056: CUI: Advanced Imaging of Matter (390715994)}, pid = {G:(DE-HGF)POF4-631 / G:(DE-HGF)POF4-6G2 / G:(GEPRIS)328961117 / G:(GEPRIS)390715994}, experiment = {EXP:(DE-H253)F-BL1-20150101}, typ = {PUB:(DE-HGF)16}, eprint = {2502.16572}, howpublished = {arXiv:2502.16572}, archivePrefix = {arXiv}, SLACcitation = {$\%\%CITATION$ = $arXiv:2502.16572;\%\%$}, doi = {10.1038/s41598-025-04905-5}, url = {https://bib-pubdb1.desy.de/record/629859}, }
