By solving the equation of motion, the formula was derived for the dissociation time of the Morse oscillator. The dissociation time of oscillator is a characteristic physical parameter of chemical bond whose value depends on the parameters of potential curve. It is important for the selective excitation of chemical bond in a molecule in connection with the progress in femtosecond laser technique. The time required to break the bond must be of the order of a few hundred femtoseconds.
