Quantum theory of D+H/sub 2/ rearrangement collision: Effects of vibrational excitation

Journal Article · · Phys. Rev. Lett.; (United States)
A quantum mechanical approach is used to calculate the cross sections and rate constants of D+H/sub 2/(v/sub ..cap alpha../=1,0) ..-->.. DH(v/sub ..beta../=0,1)+H. With v/sub ..cap alpha../=0, present results are in agreement with classical calculation. With v/sub ..cap alpha../=1, cross sections for the vibrational adiabatic transition (v/sub ..cap alpha../=1 to v/sub ..beta../=1) is an order of magnitude larger than that for the vibrational nonadiabatic transition (v/sub ..cap alpha../=1 to v/sub ..beta../=0). This result is in agreement with recent experiments but in disagreement with classical-trajectory calculation.
