Rates of Reaction of Atomic Oxygen III. Spiropentane, Cyclopentane, Cyclohexane, and Cycloheptane.

Rate constants have been measured from 307 to 652 K for the reactions of atomic oxygen (O3P) with spiropentane, cyclopentane, cyclohexane, and cycloheptane. The derived Arrhenius parameters are k(sp - C5H8) = 1013.60±0.10 exp[(-2890 ± 100)/T], k(cy - C5H10) = 1014.10±0.09 exp[(-2210 ± 100)/T], k(cy - C6H12) = 1014.35±0.09 exp[(-2350 ± 100)/T], and (cy - C7H14) = 1014.46±0.13 exp[(-2230 ± 100)/T] all in units of cm3 mol-1 s-1.
