Experimental and quantum dynamical study on an asymmetric insertion reaction:: State-to-state dynamics of O(1D)+HD(1Σg+,υ'=0,j'=0)→OH(2Π,υ'',N'')+D(2S)

Quantum-state-resolved differential cross sections of the O(D-1)+HD -> OH+D reaction at the collision energy of 7.11 kJ/mol has been determined experimentally and theoretically. The results of the time-dependent wave-packet calculations are overall in good agreement with the crossed beam scattering data, providing a benchmark example of an asymmetric insertion reaction at the state-to-state scattering level. The good agreement between experiment and theory suggests that the underlying ground potential energy surface is generally correct and that the nonadiabatic effect involving the electronic excited pathway is apparently small in this system.
