  This article presents a detailed study of the photodissociation probability
of D_{2}^{+} for a wide range of photon energy. One dimensional numerical
calculations have been performed to provide the best possible physical
quantities that characterize the vibrational trapping or bond hardening effect
during the photodissociation dynamics. These results undoubtedly show that the
nodes of the nuclear vibrational wave packets play a decisive role in the
vibrational trapping, in addition to the current understating of this
phenomenon.
