Although in principle it should be possible to use carefully prepared laser pulse sequences to control the outcome of chemical reactions such as photodissociation, in practice it is difficult to anticipate all of the possible outcomes as different states interact on different time scales. Assion et al. (p. 919) circumvent this difficulty by using an evolutionary algorithm to adjust the input laser pulse to a reaction to maximize formation of a particular product. Tailoring of femtopulse sequences allowed either of two different bond-cleaving reactions of an iron complex to be selected.
