    Recent state-resolved experiments have shown that rotational energy transfer in collisions of vibrationally excited spherical top molecules is remarkably selective with respect to the fine structure components of the rovibrational states. It is shown that this selectivity can be explained by...

    Selective vibrational excitation permits control of the outcome of a reaction with two competing channels. The thermal reaction of CH[sub 3]D with Cl ([sup 2]P[sub 3/2]) yields two reaction products: CH[sub 3] from the D-atom abstraction and CH[sub 2]D from the H-atom abstraction. We prepare the...
