|Title:||Quantum theory for transition state absorption||Authors:||Lee, S.-Y.
|Issue Date:||25-Aug-1989||Citation:||Lee, S.-Y.,Pollard, W.T.,Mathies, R.A. (1989-08-25). Quantum theory for transition state absorption. Chemical Physics Letters 160 (5-6) : 531-537. ScholarBank@NUS Repository.||Abstract:||A time-dependent quantum model involving two wave packets on two excited-state surfaces is presented to describe absorption (or emission) from the transition state of a chemical reaction. The connection between the quantum result and existing classical theories is shown. The model ia applied to the direct dissociation of ICN* and gives results in good agreement with experiment. The dissociation time - the time to half-maximal absorption - is almost invariant with the pulse width but is dependent on the probe wavelength. A lower absorption plateau and a longer dissociation time is predicted for probe energies above the asymptotic resonance energy. © 1989.||Source Title:||Chemical Physics Letters||URI:||http://scholarbank.nus.edu.sg/handle/10635/76846||ISSN:||00092614|
