Vibrational wave-packet dynamics of photodissociation of a linear triatomic BAB-type molecule under intense nonstationary radiation field condition is theoretically studied. We clarify how the wave-packets on the ground and excited adiabatic potential surfaces are coupled with each other through the molecule-laser field interaction. The excited state wave-packet is localized with double maximum structure, and the photodissociation process is suppressed during the intense molecule-radiation field interaction. It is also clarified how oscillatory behavior in intensity signals in femtosecond transition state experiments originates from the wave-packet propagation on the two-dimensional potential surface of the excited state after termination of the pulsed laser. The final momentum distribution of the photodissociation fragments is evaluated, and the fragment formation mechanism is discussed.
