Femtosecond Transition-state Dynamics
Since the early days of the transition-state theory of Eyring, Evans and Polanyi,' the fleeting nature of the state as the reaction proceeds from reagents to products has been known. The lifetime of the state is typically s, and hence to observe these transition states in real time the temporal resolution must be on the femtosecond scale. Progress has been made in probing transition states of e...
متن کاملFemtosecond vibrational transition-state dynamics in a chemical reaction
When excited directly, complexes in transition states undergo nuclear motions characteristic of bound, quasibound, or unbound dynamics. In elementary reactions, the motions are on the femtosecond time scale and depend on the dimensionality of the potential.’ For example, in the reaction ABA*+ +A+& there are two relevant coordinates that describe the motion of the triatomic transition state spec...
متن کاملRelational state transition dynamics
Basic concepts of classical dynamics are analysed in the simple mathematical setting of state transition systems, where both time and space are discrete, and no structure is assumed on the state space besides a binary transition relation. This framework proves useful to the dynamical analysis of computations and biomolecular processes. Here a relational formulation of this framework is presente...
متن کاملReprint of: Femtosecond transition-state spectroscopy of iodine: From strongly bound to repulsive surface dynamics
Article history: Available online 21 August 2013 The application of femtosecond transition-state spectroscopy (FTS) to molecular iodine is reported. The real-time motion of wave packets prepared coherently in the bound B state is observed. In addition, the motion is probed near and above the dissociation limit for the reaction: I2 ? I (P3/2) + I⁄(2P1/2). FTS measurements of the dynamics on repu...
