The Cl35(P3∕22) atoms are aligned by two mechanisms: (1) the time-dependent transfer of rotational polarization of the HCl35(v=2,J=1,M=0) molecule to the Cl35(P3∕22) nuclear spin [which is conserved during the photodissociation and thus contributes to the total Cl35(P3∕22) photofragment atomic polarization] and (2) the alignment of the Cl35(P3∕22) electronic polarization resulting from the photoexcitation and dissociation process. The total alignment of the Cl35(P3∕22) photofragments from these two mechanisms was found to vary as a function of time delay between the excitation and the photolysis laser pulses, in agreement with theoretical predictions. We show that the alignment of the ground-state Cl35(P3∕22) atoms, with respect to the photodissociation recoil direction, can be controlled optically.

Vibrational excitation of the perdeuteromethane is via direct infrared pumping. The reaction is initiated by photolysis of molecular chlorine at 355nm. The nascent methyl radical product distribution is measured by 2+1 resonance-enhanced multiphoton ionization at 330nm. The resulting CD3 state distributions reveal a preference to remove all energy available in the most excited C–D oscillator. Although the energetics are nearly identical, the authors observe strong mode specificity in which the CD3 state distributions markedly differ between the three Cl-atom reactions. Reaction with CD4 prepared in the ∣3000⟩ mode leads to CD3 products populated primarily in the ground state, reaction with CD4 prepared in the ∣2100⟩ mode leads primarily to CD3 with one quantum of stretch excitation, and reaction with CD4 prepared in the ∣1110⟩ mode leads primarily to CD3 with one quantum of C–D stretch excitation in two oscillators. There are some minor deviations from this behavior, most notably that the Cl atom is able to abstract more energy than is available in a single C–D oscillator, as in the case of ∣2100⟩, wherein a small population of ground-state CD3 is observed. These exceptions likely result from the mixings between different second overtone stretch combination bands. They also measure isotropic and anisotropic time-of-flight profiles of CD3 (ν1=1,2) products from the Cl+CD4 ∣2100⟩ reaction, providing speed distributions, spatial anisotropies, and differential cross sections that indicate that energy introduced as vibrational energy into the system essentially remains as such throughout the course of the reaction.}, number={4}, journal={The Journal of Chemical Physics}, publisher={AIP Publishing}, author={Martin, Marion R. and Ankeny Brown, Davida J. and Chiou, Albert S. and Zare, Richard N.}, year={2007}, month={Jan}, pages={044315} }

Of the potential energy surfaces (PES) we explored, the direct dynamics calculations using the B3LYP/6-31G** density functional theory PES provide the best agreement with the experimental measurements. This agreement is likely due to the better overall description that B3LYP provides for geometries well removed from the minimum energy path, even though its barrier height is low by approximately 0.2 eV. In contrast to previous theoretical calculations, the angular distributions on this surface show behavior associated with a stripping mechanism, even at collision energies only approximately 0.1 eV above the reaction barrier. Other potential energy surfaces, which include an analytical potential energy surface from Espinosa-García and a direct dynamics calculation based on the MSINDO semiempirical Hamiltonian, are less accurate and predict more rebound dynamics at these energies than is observed. Reparametrization of the MSINDO surface, though yielding better agreement with the experiment, is not sufficient to capture the observed dynamics. The differences between these surfaces are interpreted using an analysis of the opacity functions, where we find that the wider cone of acceptance on the B3LYP surface plays a crucial role in determining the integral cross sections and angular distributions.}, number={2}, journal={The Journal of Physical Chemistry A}, publisher={American Chemical Society (ACS)}, author={Camden, Jon P. and Hu, Wenfang and Bechtel, Hans A. and Brown, Davida J.

The theoretical results are based on quasiclassical trajectories from (1) first principles direct dynamics calculations (B3LYP/6-31G), (2) an empirical surface developed by Espinosa-García [J. Chem. Phys. 2002, 116, 10664] (EG), and (3) two semiempirical surfaces (MSINDO and reparametrized MSINDO). We find that most of the energy appears in product translation at energies just above the reactive threshold; however, HD vibration and rotation become quite important at energies above 1 eV, each accounting for over 20% of the available energy above 1.5 eV, according to the B3LYP calculations. The barrier on the B3LYP surface, though being later than that on EG, predicts significantly higher HD vibrational excitation than EG. This deviation is contradictory to what would be expected on the basis of the Polanyi rules and derives from modest differences in the potential energy surfaces. The CD3 internal energy is generally quite low, and we present detailed rotational state distributions which show that the CD3 rotational distribution is largely independent of collision energy in the 0.75-1.95 eV range. The most populated rotational levels are N = 5 and 6 on B3LYP, with most of that excitation being associated with motion about the C2 axes, rather than C3 axis, of the CD3 product, in good agreement with the experimental results. Through our extensive studies in this and previous work concerning the scattering dynamics, we conclude that B3LYP/6-31G provides the best available description of the overall dynamics for the title reaction at relatively high collision energies.}, number={9}, journal={The Journal of Physical Chemistry A}, publisher={American Chemical Society (ACS)}, author={Hu, Wenfang and Lendvay, György and Troya, Diego and Schatz, George C. and Camden, Jon P. and Bechtel, Hans A. and Brown, Davida J.

Spatially separated output pulses are produced by directing the incident beam into the cavity in such a way that it walks in a direction transverse to the optical axis as it propagates between the two mirrors. This effect may be achieved either by a plane-parallel resonator oriented at a nonzero angle of incidence or by a wedge cavity, for which one of the mirrors is set at an angular offset. The spatially resolved output train may then be related to the time-dependent attributes of the resonator and the molecules it encloses. Time resolution is controlled by the separation of the mirrors, wedge geometry, and the angle of incidence. A time resolution of better than 4 ps is achieved using a 500 µm mirror separation and a 20° angle of incidence.}, number={14-15}, journal={Molecular Physics}, publisher={Informa UK Limited}, author={Rypkema, H.
