摘要
We investigate the chaotic dynamics of normal mode molecules from the classical point of view using the coupling Morse oscillators.New interesting phenomena of the fractured tori and the cross of tori on the poincaré section,which go against our traditional understanding,are found and investigated.Also,we find that the phenomenon of tori cross is a siggature of the single bond's energy beyond the total vibrational energy.Finally,a method to improve this scarcity is proposed.
