The Arrhenius rate coefficients (in units of cm(3)molecule(-1) s(-1)) over the temperature range 263-371 K were determined from the kinetic data obtained as k(1) = (5.5 +/- 1.0) x 10(-12) exp (836 +/- 54)/T; k(2) = (6.9 +/- 0.9) x 10(-12) exp (744 40)/T; k(3) = (10 +/- 1) x 10(-12) exp (652 +/- 27)/T; and k(4) = (4.0 +/- 0.4) x 10(-12) exp (783 +/- 32)/T. At 298 K, the rate coefficients obtained by the two methods for each of the alcohols studied were in good agreement. The results are presented and compared with those obtained previously for the same and related reactions of OH radicals. Reactivity factors for substituent groups containing the hydroxyl group are determined. The atmospheric implications for the studied alcohols are considered briefly.
