Reaction rate of vibrationally excited hydroxyl with ozone.
The reaction of vibrationally excited hydroxyl with ozone was studied in a fast-flow system by observing the effect of ozone concentration on the intensity of hydroxyl emission bands in the 1.4-micro to 2.2-micro wavelength region. Fourier transform spectroscopy was used to obtain spectra of the faint emissions from the excited hydroxyl. Rate constants for the ozone-hydroxyl reaction were calculated for vibrational levels nu = 2 to nu = 9. The rate constants increased with vibrational level in a regular manner up to nu = 5. An abrupt increase occurred for nu = 6 relative to nu = 5, which may suggest a change in mechanism beginning at nu = 6.
