Quantum state specific reactant preparation in a molecular beam by rapid adiabatic passage

Rainer Beck, Bruce Yoder, Phil Morten Hundt, Maarten Eduard van Reijzen, Helen Jane Chadwick

Highly efficient preparation of molecules in a specific rovibrationally excited state for gas/surface reactivity measurements is achieved in a molecular beam using tunable infrared (IR) radiation from a single mode continuous wave optical parametric oscill ...

Alignment dependent chemisorption of vibrationally excited CH4(3) on Ni(100), Ni(110), and Ni(111)

Rainer Beck, Régis Bisson, Bruce Yoder, Phil Morten Hundt

We present a stereodynamics study of the dissociative chemisorption of vibrationally excited methane on the (100), (110), and (111) planes of a nickel single crystal surface. Using linearly polarized infrared excitation of the antisymmetric C–H stretch nor ...

Steric Effects in the Chemisorption of Vibrationally Excited Methane on Ni(100)

Rainer Beck, Régis Bisson, Bruce Yoder

Newly available, powerful infrared laser sources enable the preparation of intense molecular beams of quantum-state prepared and aligned molecules for gas/surface reaction dynamics experiments. We present a stereodynamics study of the chemisorption of vibr ...

Steric Effects in the Chemisorption of Vibrationally Excited Methane on Nickel

Bruce Yoder

In this thesis, steric effects in the dissociative chemisorption of quantum state-prepared methane on single crystal surfaces of nickel (Ni(100) and Ni(110)) are detected and quantified for the first time. Exploiting a new, continuous-wave, high-power, sin ...

State-Resolved Reactivity of CH4(2ν3) on Pt(111) and Ni(111): Effects of Barrier Height and Transition State Location

Rainer Beck, Plinio Maroni, Thanh Tung Dang, Marco Sacchi, Régis Bisson, Bruce Yoder

Quantum state-resolved sticking coefficients on Pt(111) and Ni(111) surfaces have been measured for CH4 excited to the first overtone of the antisymmetric C-H stretch (2ν3) at well defined kinetic energies in the range of 10-90 kJ/mol. The ground state rea ...
