Isomer distinction: Using femtosecond‐laser mass spectrometry structural isomers of xylene, that exhibit almost identical conventional electron impact mass spectra, can be distinguished. For femtosecond‐pulse ionization the ion yields of the atomic fragments C + and C 2+ carry the memory of the structural identity of their parent molecules.
