In reactions between CN radicals and a pentane solute in dichloromethane, the bridging complex continues to dominate the CN signal decay. In addition, as the pentane concentration increases, the more abundant bridging complex begins to dominate the HCN product growth as well. This bridging complex dominance led us to compare the CN signal decay for a set of 15 other solutes to analogous Cl radical reactions. The CN bridging complex generally reacts more slowly than Cl, likely due to greater complex stability and steric constraints. For alcohol solutes, however, the rates are about the same, suggesting that OH group interactions can influence the dynamics. Cl substituents on solutes and solvents consistently decrease their reactivity toward both complexes. Observing a subset of solutes in chloroform and 1, 1, 1-trichloroethane reveals minimal solvent effects.Figure 2.13 Wiring diagram for infrared array detection.
