Strong laser fields exert forces comparable to, or exceeding, the forces which bind atoms to molecules. We exploit this physics to achieve selectivity in the dissociation of triatomic cations, using a simple, intuitive approach. We propose a class of molecules for which a strong bond can be preferentially dissociated over a weak bond using a strong infrared pulse with very simple pulse parameters. Selectivity is demonstrated for a model system of the type ABC +.
