TL;DR: In this paper, a three-dimensional (3D) ion velocity imaging method was developed to measure the product velocity distributions in crossed molecular beam experiments, while maintaining conventional two-dimensional velocity mapping, the third velocity component was mapped linearly to the ion time of flight.

TL;DR: A detailed analysis of the quantum dynamics establishes that a reactive resonance localized in the transition-state region is responsible for these remarkable observations in the F+HD reaction.

TL;DR: This work measured the relative efficiencies of vibration and translation in promoting the gas-phase reaction of CHD3 with the Cl atom to form HCl and CD3 and observed that C–H stretch excitation is no more effective than an equivalent amount of translational energy in raising the overall reaction efficiency.

TL;DR: An in-depth experimental study of the reactivity effects exerted by reactant C-H stretching excitation in a prototypical early-barrier reaction, F + CHD3 finds that the vibration hinders the overall reaction rate, inhibits scission of the excited bond itself, and influences the coproduct vibrational distribution despite being conserved in the CHD2 product.
