    • Although concertedness is usually defined in terms of a potential energy surface, the absence or presence of a given intermediate may vary when free energy is considered.(2) In addition, some intermediates have very small barriers for conversion into other species, leading some to prefer definitions based on lifetimes rather than the presence or absence of minima on a potential energy surface. For a recent study that deals with such issues, see

    • A classic paper on the issue that generated considerable debate: The definitions used in this paper: "In our terminology a synchronous reaction is one where all the bond-making and bond-breaking processes take place in unison, having all proceeded to comparable extents in the transition state. A concerted reaction is one that takes place in a single kinetic step without necessarily being synchronous. A two-stage reaction is concerted but not synchronous, some of the changes in bonding taking place in the first part of the reaction, followed by the rest. A two-step reaction takes place in two kinetically distinct steps, via a stable intermediate."
