IVR: Its Coherent and Incoherent Dynamics
- Ahmed H. Zewail
Femtochemistry: Ultrafast Dynamics of the Chemical Bond01 Sep 1994
Preview Abstract
In this paper, we discuss the dynamics of intramolecular vibrational-energy redistribution (IVR) in two limits: the coherent and incoherent limits. These descriptions are introduced to account for experiments done in time and frequency domains. We present a more general model for IVR, namely the model of overlapping resonances, which describes coherence (quantum beats), congestion and nonexponentional decays.
