The ultrafast vibrational and dissociation dynamics of polyatomic radical cations can be investigated with femtosecond pump‐probe techniques such as femtosecond time‐resolved mass spectrometry (FTRMS). Observed ion yield oscillations arise from coherent excitation of specific vibrational modes upon ionization, as illustrated for 2‐, 3‐, and 4‐nitrotoluene as well as dimethyl, diethyl, and diisopropyl methylphosphonate.
