A good way to show the formation of products is to plot interatomic distances as a function of time. In Fig 35.2, RAB and RBC for the H2 + H reaction are shown. In the reactive collision shown in the figure, the switch over to the products begins after about 25 fs (femtoseconds) and the separation into the products is complete by 40 fs.
