State-correlation matrix of the product pair from F+CD4 → DF(ν′)+CD3(0 v2 0 0)

The title reaction was investigated under crossed-beam conditions at three different collision energies, E-c = 8.4, 2.76 and 1.46 kcal mol(-1). The combination of using a (2 + 1) resonance-enhanced multiphoton ionization for tagging state-specific CD3 products and exploiting a time-sliced velocity imaging for ion detection allows us to reveal the coincident information of the two product pairs in a state-correlated manner. The pair-correlated results are reported for the two product vibrators- (v(2) = 0, v') (v(2) = 1, v'), (v(2) = 2, v') and (v(2) = 3, v')-and the dynamics attributes we examined include product state distributions, energy disposals and angular distributions. Together with our earlier communications [J. Lin, J. Zhou' W. Shiu, and K. Liu, Science 2003, 300, 966, ref. 14 and J. Lin, J. Zhou, W. Shiu, and K. Liu, J. Chem. Phys. 2003, 119, 4997, ref. 15], a rather complete picture of the correlated dynamics of the title reaction emerges. One of the major findings, the anti-correlated excitations of the two product vibrators at all four energies of this study, can qualitatively be understood by kinematics arguments.
