摘要
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 C2+ carry the memory of the structural identity of their parent molecules.
