Rate constants of chlorine atom (Cl • ) reactions ( k Cl• ) determined using a large variation of experimental methods, including transient measurements, steady-state and computation techniques, were collected from the literature and were discussed together with the reaction mechanisms. The k Cl• values are generally in the 10 8 –10 9 mol −1 dm 3 s −1 range when the basic reaction between the Cl • and the target molecule is H-...
