“…The reactive scattering of a light atom with a heavy diatomic has recently attracted considerable interest due to the propensity for migratory dynamics [1][2][3][4] in such reactions and the possibility of significant correlation effects being observed between the final angular momenta. 5 In the preceding paper 6 a model for the breakdown of long-lived complex dynamics in a light plus heavy-heavy (L + HH) reaction has been applied to O + Br2 reactive scattering in order to rationalise the increased prominence of the backward scattering observed at high initial translational energy.…”

Reactive scattering of O atoms with I2 molecules has been studied at an initial translational energy E~43 kJ mol−1 using cross-correlation time-of-flight analysis with resolution improved overprevious measurements. The broad centre-of-mass differential cross section favours the backward hemisphere with a product translational energy distribution lying above the distribution observed at lower initial translational energy but below the microcannonical RRHO distribution. However, a minor component with very low product translational energy favours the forward hemisphere. The observed scattering is attributed to a strongly bent OII triplet complex intermediate with a lifetime shorter than the period of overall rotation of the axis of the heavy II diatomic but long compared with the period of vibrational and rotational motion of the light O atom.

We have performed a crossed beam study of the F+I2→IF+I reaction. The IF product was detected by the LIF technique, using a cw single frequency dye laser. About 10 000 lines belonging to the B–X system of IF have been thus recorded. These lines have been assigned and the populations of about 1300 rovibrational levels of the X state were deduced from their intensities. This analysis takes into account the coherent saturation regime of the excitation process. In the present work, only the high vibrational levels of the X state (v″=8–20) have been studied. A striking result is the observation of bimodal rotational distributions for several vibrational levels: the rotational distribution presents a plateau and a peak for high rotational quantum numbers. The vibrational distribution presents a peak centered at v″=13, and as we have shown that the v″=0 peak observed by other authors is in fact an experimental artifact, the general features of the energy disposal in this reaction are now well known.
