    Collinear (He,HD+) and (He,DH+) collisions: Transition state resonances and dynamics by time-dependent quantal wave packet approach (1996)
    College Park, Md. : American Institute of Physics (AIP)

    Notizen: We examine the possibility of existence of dynamical resonances in collinear (He,HD+) and (He,DH+) collisions by analyzing their respective transition state spectra on the McLaughlin-Thompson-Joseph-Sathyamurthy potential energy surface (PES). The spectra are computed by Fourier transforming the temporal autocorrelation function, C(t), of the initial wave packet. Some of the well resolved resonances are analyzed by computing their eigenfunctions and lifetimes. The vibrational state (v) - selected energy resolved reaction probabilities (PRv(E)) for collinear (He,HD+) and (He,DH+) collisions are also calculated on the same PES by computing the reactive flux in the product channel. The PRv(E) values for HeHD+ show a characteristic staircase-like structure that can be related to threshold resonances. The PRv(E) values for HeDH+ on the other hand, are highly oscillatory, in keeping with the densely packed transition state spectrum. © 1996 American Institute of Physics.

    A time-dependent quantum mechanical investigation of dynamical resonances in three-dimensional HeH2+ and HeHD+ systems (2000)

    Notizen: Bound and quasibound states of HeH2+ and HeHD+ in three dimensions, for zero total angular momentum, have been computed using a time-dependent quantum mechanical approach. Time evolution of a carefully chosen wave packet in the interaction region is followed and the time correlation function evaluated and its Fourier transform obtained. The resulting eigenvalue spectrum and the corresponding eigenfunctions are examined to characterize the nature of the dynamical resonances for the system. It becomes clear that at low energies the quasibound states can be assigned readily in terms of local modes. While some of the higher energy state eigenfunctions resemble the hyperspherical modes, a large number of them cannot be assigned easily, suggesting irregular dynamics, in keeping with a large number of unstable periodic orbits known for the system. © 2000 American Institute of Physics.

    Theoretical investigation of Jahn–Teller and pseudo-Jahn–Teller coupling effects on the photoelectron spectrum of allene (1999)

    Notizen: The valence photoelectron spectrum of allene (C3H4) pertinent to the A˜ 2E/B˜ 2B2 interacting electronic manifold of the corresponding cation (C3H4+) is theoretically calculated and compared with the most recent high resolution He I excited experimental recording of Baltzer et al.[Chem. Phys. 196, 551 (1995)]. A model diabatic Hamiltonian within the linear vibronic coupling scheme and ab initio calculated coupling parameters are employed in our investigations. While the resolved vibrational progressions in the photoelectron band at low energies can be attributed to the E⊗B Jahn–Teller activity within the A˜ 2E electronic manifold, the diffuse structure in the photoelectron band at high energies is found to emerge from the mixing of the A˜ 2E electronic manifold with the B˜2B2 electronic state via degenerate vibrational modes. The latter demonstrates the importance of the pseudo-Jahn–Teller type of interactions in the photoelectron spectrum of allene. © 1999 American Institute of Physics.

    Bound states and time-dependent dynamics of the N2H+ molecular ion in its ground electronic state. I. 2D treatment (1997)

    Notizen: The ground-state potential energy surface (PES) for linear arrangements of the N2H+ molecular ion is numerically computed by the multireference single- and double-excitation configuration interaction (MRD-CI) technique. An analytical representation of the potential energy function is obtained by fitting a power series in the Simons–Parr–Finlan coordinates to the numerical data. For investigating the intramolecular dynamics we describe the nuclear motion by a Gaussian wave packet located initially in the strong interaction region of the PES. The vibrational eigenvalue spectrum is calculated by Fourier transforming the time autocorrelation function. The spectrum is then analyzed statistically in the light of random matrix theory (RMT) to understand the nature of the intramolecular dynamics. We examine the short-range correlation in the spectrum through the nearest neighbor level spacing distribution P(s) and the long-range correlation through Δ3 and Σ2 statistics. The spectrum in the time domain is analyzed by computing the ensemble averaged survival probability 〈〈P(t)〉〉. The above four quantities obtained from the spectrum are compared with the distribution predicted for regular, irregular, and mixed (intermediate) spectra by the RMT. We find the system is of mixed type and the fractional irregularity is 0.7±0.05. In order to reveal a possible correspondence to the classical dynamics, we have carried out the spectral analysis of the dynamical variables for classical trajectories over a wide range of internal energies. In addition the classical dynamics of proton collisions with N2 molecules has also been preliminarily studied on the same PES, in particular the dependence of the final vibrational action nf on the initial vibrational phase φi of N2 and, furthermore, the Poincaré surface-of-section superimposed with the zero-order separatrix; we find a large number of trapped trajectories. © 1997 American Institute of Physics.

    Impact of nonadiabatic coupling between the conically intersecting X˜ 2A1 and A˜ 2B2 states of NO2 on the negative ion photoelectron spectra of NO2− (1999)
    College Park, Md. : American Institute of Physics (AIP)

    Notizen: Negative ion photoelectron spectra of NO2− at 266 nm (4.660 eV) and 351 nm (3.532 eV) are theoretically calculated and compared with earlier experimental findings. A diabatic model Hamiltonian with linear vibronic coupling between the conically intersecting X˜ 2A1 and A˜ 2B2 states of NO2 is employed for this purpose. While the linear vibronic coupling model successfully reproduces the low resolution experimental photoelectron spectrum at 266 nm, second order coupling terms are necessary for the high resolution spectrum at 351 nm. The vibronic structure of the X˜ 2A1 state of NO2 in the photoelectron spectrum is found to be almost unaffected by the nonadiabatic coupling, whereas, the latter has a strong impact on the vibronic structure of the A˜ 2 B2 state. The magnitude of the vibronic coupling constant, which has otherwise been overestimated by earlier theoretical studies, is calculated ab initio and its limits of validity are confirmed by the results from different ab initio calculations. © 1999 American Institute of Physics.

    Resonances in He + H2+→HeH+ + H reaction in three-dimensions: Energy resolved total reaction probabilities by the time-dependent wave packet method (1997)

    Notizen: Vib-rotational state-selected and energy resolved total reaction probabilities for the title reaction in three dimensions are calculated on the McLaughlin–Thompson–Joseph–Sathyamurthy potential energy surface, by the time-dependent wave packet (WP) method for the total angular momentum J=0. The probabilities as obtained by the time-energy mapping of the reactive flux of the WP across a dividing surface in the asymptotic product channel reveal a large number of narrow resonances, in agreement with the time-independent quantum mechanical results available in the literature. While initial vibrational excitation of H2+ is shown, in general, to enhance the reaction probability considerably, in agreement with the experimental observations, rotational excitation has only a marginal influence. © 1997 American Institute of Physics.
