Inner-shell photoelectron spectroscopy provides an element-specific probe of molecular structure, as core-electron binding energies are sensitive to the chemical environment. Short-wavelength femtosecond light sources, such Free-Electron Lasers (FELs), even enable time-resolved site-specific investigations photochemistry. Here, we study ultraviolet photodissociation prototypical chiral molecule 1-iodo-2-methylbutane, probed by extreme-ultraviolet (XUV) pulses from Free-electron LASer in Hamburg (FLASH) through ultrafast evolution iodine 4d energy. Methodologically, employ electron-ion partial covariance imaging a technique isolate otherwise elusive features two-dimensional spectrum arising different photofragmentation pathways.
