## Abstract Optimal control theory has been applied in the past for the design of RF pulses for selective excitation. This was the outcome of having established the controllability of the MR spin system for the selective excitation problem. βMinimum distanceβ was the main formulation used for the s

β¦ Synopsis
We present a practical method for controlling non-adiabatic photodissociation on the basis of wave-packet theory. The ratio of the two reaction channels in the photodissociation of NaI can be controlled by changing the pulse width of two successive short pulses. We can control the reaction most effectively when we use a chirped pulse with approximately optimized chirp parameters.

By a wavepacket propagation, we demonstrate the possibility of controlling the photodissociation branching ratio between two fragment channels by a single ultrashort linearly chirped laser pulse. It is found that a negatively chirped pulse of a moderate chirp rate completely prohibits the production
