Unraveling the Nature of Chemical Reactivity of Complex Systems
Abstract
Exciting a stretching mode of a bond in a reactant should increase the likelihood of the bond breaking during a chemical reaction or, at the very least, have no impact on the reaction, according to conventional wisdom. A series of crossed molecular beam studies of the Cl + CHD3/CH4/CH2D2 reactions, performed at IAMS, confirm this expectation. However, similar experiment on F + CHD3 has shown that, counter-intuitively, exciting the C-H bond effectively impedes its breakage to form HF + CD3. The rate of the other possible reaction pathway - which leads to DF and CHD2 - also slows down.
