	abstract = {The research and development of new substrates for use in surface-enhanced spectroscopy is primarily motivated by the ability to tune such substrates to provide maximum signal enhancement and therefore lower detection limits. We examined a series of multilayer nanoparticle (NP) arrays with between 1 and 17 NP layers using two nonlinear optical (NLO) techniques: Coherent anti-Stokes Raman scattering (CARS) and second harmonic generation (SHG). The CARS signal of oxazine 720 was monitored at 1600 cm(-1) using a 709-nm pump beam and an 800-nm stokes beam. Maximum signal was observed for 11 NP layers and is attributed to the matching of the CARS signal and the substrate surface plasmon excitation at 637 nm. The CARS signal for the 3000-cm(-1) C-H stretching vibration showed maximum enhancement at 13 NP layers. The maximum SHG signal enhancement occurred at 13 NP layers, with a 50-fold overall enhancement of the SHG signal. We demonstrate that the NP-containing substrates can be tuned to provide maximum NLO response based on the number of NP depositions and the wavelength(s) involved in the NLO experiments. These multilayer NP arrays yield a stable and modular spectroscopic substrate advantageous for a variety of surface-enhanced spectroscopic techniques.},

	abstract = {The photodissociation of HCl+ on two coupled potential surfaces is studied in the long wavelength regime with a semiclassical method employing classical trajectories and a hopping algorithm. Dissociation probabilities, product kinetic energy distributions, and branching ratios are presented. In addition, two mechanisms are introduced to explain trends in these properties. One mechanism produces large product kinetic energies and is an extension to two-coupled surfaces of the "wagging tail" mechanism seen in a previous one-surface study [M. Thachuk and D. M. Wardlaw, J. Chem. Phys. 102, 7462 (1995)]. The other mechanism is an extended barrier-suppression mechanism and accounts for the bulk of the product kinetic energy distribution, and in particular rationalizes the low energy part of these distributions as well as the branching ratios. It is shown that most of the trajectories undergo at most one nontrivial hop before dissociating so that the dynamics is dominated by the motion near the barrier to dissociation. This provides a simple, intuitive model for understanding the overall dynamics. (C) 2000 American Institute of Physics. [S0021-9606(00)00130-6].},
