Quantum-state-resolved reactivity of overtone excited CH4 on Ni(111): Comparing experiment and theory

Rainer Beck, Phil Morten Hundt, Maarten Eduard van Reijzen

Quantum state resolved reactivity measurements probe the role of vibrational symmetry on the vibrational activation of the dissociative chemisorption of CH4 on Ni(111). IR-IR double resonance excitation in a molecular beam was used to prepare CH4 in three ...

Bond-Selective and Mode-Specific Dissociation of CH3D and CH2D2 on Pt(111)

Rainer Beck, Phil Morten Hundt, Hirokazu Ueta, Maarten Eduard van Reijzen

Infrared laser excitation of partially deuterated methanes (CH3D and CH2D2) in a molecular beam is used to control their dissociative chemisorption on a Pt(111) single crystal and to determine the quantum state-resolved dissociation probabilities. The excl ...

Vibrational Activation of Methane Chemisorption: The Role of Symmetry

Rainer Beck, Phil Morten Hundt, Hirokazu Ueta, Maarten Eduard van Reijzen

Quantum state-resolved reactivity measurements probe the role of vibrational symmetry on the vibrational activation of the dissociative chemisorption of CH4 on Pt(111). IR–IR double resonance excitation in a molecular beam is used to prepare CH4 in all thr ...

Vibrationally Promoted Dissociation of Water on Ni(111)

Rainer Beck, Phil Morten Hundt, Maarten Eduard van Reijzen

Water dissociation on transition-metal catalysts is an important step in steam reforming and the water-gas shift reaction. To probe the effect of translational and vibrational activation on this important heterogeneous reaction, we performed state-resolved ...

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 ...

The sticking probability of D2O-water on ice: Isotope effects and the inﬂuence of vibrational excitation

Rainer Beck, Régis Bisson, Phil Morten Hundt

The present study measures the sticking probability of heavy water (D2O) on H2O- and on D2O-ice and probes the inﬂuence of selective OD-stretch excitation on D2O sticking on these ices. Molecular beam techniques are combined with infrared laser excitation ...

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 ...
