Laser control of chemical reactions : Orders of magnitude control over the relative yield of products is achieved using binary shaped femtosecond laser pulses. Transform‐limited pulses (‐ ‐ ‐ ‐ ‐) produce ions with an intact aromatic ring; highly modulated pulses (—) yield smaller mass fragments. The pathway involving isomerization of the nitro group is insensitive to phase modulation.
