摘要：

Mode specific resonance decay is demonstrated by Fast Fourier Transform (FFT) time propagation of resonance wave packets for an ABA molecule modeled by coupled Morse oscillators. Fast and flow decay correlates with local and hyperspherical modes which have their wave function lobes directed towards dissociation exits and ridges of the potential, respectively, in excellent analog to G. Hose and H. S. Taylor's analysis of the Henon-Heiles system. The decay shows no correlation with energy or symmetry. The FFT method yields details of the decay mechanism. The results are related to observations of mode specific unimolecular processes in bulk.
