Abstract :
We report rate coefficients for the relaxation of OH(v = 1) by O2 and N2O as a function of temperature. The rate coefficients for relaxation (in units of 10−13 cm3 molecule−1 s−1) can be fit by the following expressions: for OH ( v = 1 ) + O 2 between 204 and 371 K: k = ( 0.50 ± 0.06 ) exp ( ( 342 ± 32 ) / T ) ; for OH ( v = 1 ) + N 2 O between 243 and 372 K: k = ( 1.08 ± 0.08 ) exp ( ( 162 ± 22 ) / T ) . The results are discussed in terms of the possible mechanisms for relaxation, especially the influence of the weak chemical interaction between OH radicals and O2.
