The vibrationally excited reaction O(D) + CHD(ν = 1) has been investigated by crossed-molecular-beam experiments with a time-sliced velocity map imaging technique. Detailed and quantitative information is extracted on the C-H stretching excitation effects on the reactivity and dynamics of the title reaction, with the help of preparation of C-H stretching excited CHD molecules by direct infrared excitation. Experimental results show that the vibrational stretching excitation of the C-H bond almost does not affect the relative contributions between different dynamical pathways for all product channels. For the OH + CD product channel, the vibrational energy of the C-H stretching excited CHD reagent is channeled exclusively into the vibrational energy of the OH products. The vibrational excitation of the CHD reactant changes the reactivities for the ground-state and umbrella-mode-excited CD channels very modestly, while it significantly suppresses the corresponding CHD channels. For the CHD(ν = 1) channel, the stretching excited C-H bond of the CHD molecule acts almost as a pure spectator.
