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 ...

Efficient Stimulated Raman Pumping for Quantum-State Resolved Surface Reactivity Measurements

Thomas Rizzo, Rainer Beck, Plinio Maroni

We describe the use of stimulated Raman pumping in a molecular beam to perform quantum state resolved gas-surface reactivity measurements for molecules prepared in totally symmetric vibrational states. Vibrational states of homonuclear diatomics as well as ...

Infrared spectroscopy of hydrated amino acids in the gas phase: protonated and lithiated valine

Oleg Boyarkine, Thomas Rizzo, Rainer Beck, Sébastien Mercier, Anthi Kamariotou, Evan Rowland Williams

We report here infrared spectra of protonated and lithiated valine with varying degrees of hydration in the gas phase and interpret them with the help of DFT calculations at the B3LYP/6-31++G** level. In both the protonated and lithiated species, our resul ...

State-resolved gas-surface reactivity of methane in the symmetric C-H stretch vibration on Ni(100)

Thomas Rizzo, Rainer Beck, Plinio Maroni, Thanh Tung Dang, Marco Sacchi

The state-resolved reactivity of CH4 in its totally symmetric C-H stretch vibration (nu(1)) has been measured on a Ni(100) surface. Methane molecules were accelerated to kinetic energies of 49 and 63.5 kJ/mol in a molecular beam and vibrationally excited t ...
