| Abstract: | Hyperspherical H2O* resonances excited to energies ?1 eV above the electronic ground state H2O* → H + OH dissociation threshold have lifetimes ≈ 45 ps, at least ten times longer than near-degenerate local H2O* resonances. The results are evaluated and analysed using fast-Fourier-transform (FFT) propagation of quantum wavefunctions representing H2O stretching vibrations modeled by coupled Morse oscillators. |
