WebApr 6, 2005 · From a good reaction coordinate, one may expect a dynamically meaningful measure of the progress of a reaction. Formally, the projection operator formalism (1, 2) allows us to obtain the dynamics along a chosen coordinate, but for poor choices the projected dynamics will be highly non-Markovian with long-time memory effects.In … WebFollowing the Intrinsic Reaction Coordinate. ...
