%X 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 as Free-Electron Lasers (FELs), even enable time-resolved site-specific investigations of molecular photochemistry. Here, we study the ultraviolet photodissociation of chiral (R/S)-1-iodo-2-methylbutane, probed by XUV pulses from the Free-electron LASer in Hamburg (FLASH) through the ultrafast evolution of the iodine 4d binding energy. Methodologically, we introduce electron-ion partial covariance imaging as a technique to isolate otherwise elusive features in a two-dimensional photoelectron spectrum arising from different photofragmentation pathways. The experimental and theoretical results for the time-resolved electron spectra of the 4d<sub>3/2</sub> and 4d<sub>5/2</sub> atomic and molecular levels that are disentangled by this method provide a key step towards studying structural and chemical changes from a specific spectator site. We thus pave the way for approaching femto-stereochemistry with FELs.
