Times Cited Count：1 Percentile：6.04(Materials Science, Multidisciplinary)Ortho-to-para conversion of molecularly chemisorbed H on a Pd(210) surface at a surface temperature of 50 K is reported. A combination of a pulsed molecular beam, photo-stimulated desorption and resonance-enhanced multiphoton ionization techniques was used for probing the change in the rotational states of molecularly chemisorbed H on the surface. Our result shows that fast ortho-para conversion of chemisorbed H occurs. The conversion time was experimentally determined to be about 2 s, which is in good agreement with a previous theoretical calculation. This agreement supports that the ortho-para conversion mechanism of the molecularly chemisorbed H on Pd(210) is the two-step process based on the hyperfine-Coulomb excitation.

Times Cited Count：63 Percentile：89.43(Chemistry, Physical)Centroid molecular dynamics, CMD, is a popular method to extract approximate quantum dynamics from path integral simulations. Here we provide evidence that for condensed phases, and in particular for liquid water, CMD produces pronounced artificial red-shifts for high-frequency vibrations such as the OH stretching band. This peculiar behavior intrinsic to the CMD method is improved after applying a simple "harmonic curvature correction".

Times Cited Count：183 Percentile：98.91(Chemistry, Physical)Centroid and Ring Polymer molecular dynamics, CMD and RPMD, are two conceptually distinct extensions of path integral molecular dynamics that are able to generate approximate quantum dynamics of complex molecular systems. Both methods can be used to compute quasi-classical time correlation functions which have direct application in molecular spectroscopy; in particular to infrared spectroscopy via dipole auto-correlation functions. The performance of both methods for computing vibrational spectra of several simple but representative molecular model systems is investigated systematically as a function of temperature and isotopic substitution.

Angular dependence of tunnel ionization from a molecule in a strong laser field reflects the structure of the molecular orbital the electron tunnels from. Ours are the first measurements for a heteronuclear molecule. To determine the angle, we use circularly polarized light and detect the electron and fragment ion in coincidence. Concentrating on HCl, bond softening allows us to select the tunnel ionization from HOMO-1. The angular distribution is consistent with the shape of the orbital, modified by a contribution from the dipole moment of the neutral molecule and its cation.

While hydrogen typically chemisorbs dissociatively on a flat metal surface, it is known that hydrogen can molecularly chemisorb on stepped surfaces, such as Pd(210). In this study, using a combination of a pulsed molecular beam, photo-stimulated desorption and resonance-enhanced multiphoton ionization techniques, the rotational states of molecularly chemisorbed H are probed. We will present the rotational state distribution of photo-desorbed H, and the o-p conversion process of molecularly chemisorbed H will be discussed.

Surface defects such as step and kink affect surfaced reaction. While hydrogen typically chemisorbs dissociatively on a flat metal surface, it is known that hydrogen can molecularly chemisorb on stepped surfaces, such as Pd(210). Recently, we developed a technique to probe ortho-para conversion of adsorbed hydrogen which consists of a combination of a pulsed molecular beam, photo-stimulated desorption and resonance-enhanced multiphoton ionization techniques. We report a result of orho-para conversion time of molecularly chemisorbed H on Pd(210).

We present a direct measurement of fast Ortho-Para conversion of molecularly chemisorbed H on Pd(210) at a surface temperature of 50 K. The determined conversion time was about 2 sec, which is in reasonably agreement with a previous theoretical calculation. This agreement supports that ortho-para conversion mechanism of the molecularly chemisorbed H on Pd(210) is the two-step process based on the hyperfine-Coulomb excitation.
