Electronic Structure of Molecular Rydberg States
Chinese Physics Letters, 1992Comprehensive theoretical results of the molecular Rydberg structures with the total-electron numbers starting from 2 to 18 are reported. We attempt to elucidate: (1) systematic trends of the variation of the eigen quantum defects among those molecules, (2) characteristics of the molecular dynamics between the excited electron and the corresponding ...

Triplet Rydberg states in molecular nitrogen
The Journal of Chemical Physics, 1986A pulsed electric discharge in a pulsed supersonic jet of N2 is found to produce high densities of metastable E3Σ+gN2. Subsequent laser irradiation of these metastables results in single-photon excitation to autoionizing states. Singly charged cations are detected by time-of-flight mass spectrometry or alternatively, ejected electrons are detected by ...

Strong vibronic coupling in molecular Rydberg states
The Journal of Chemical Physics, 1984We consider the vibronic properties of molecular Rydberg states in the strong coupling (degenerate) limit of the ion core, and show how the observed optical Rydberg spectrum for such a molecule is closely related to the Franck–Condon spectrum of its Jahn–Teller ion core, regardless of the symmetry labels attached to the Rydberg electronic species ...

Rydberg states: sensitive probes of molecular structure
Chemical Physics Letters, 2003Using the isomers naphthalene and azulene, and isomeric forms of the cyclohexadiene/hexatriene system, we demonstrate that the energies of Rydberg states are sensitive to the geometrical structure of the molecular ion core. Rydberg states with low quantum numbers are conveniently accessed using multi-photon excitation via valence states, providing ...

Molecular rydberg states. Azulene and 4,6,8-trimethylazulene
Chemical Physics Letters, 1979Abstract The absorption spectra of azulene and 4,6,8-trimethylazulene are reported in the 1100–2200 A region. Two d-Rydberg series, both terminal on the first ionization potential I (I), are assigned. The lack of structure beyond the I (I) limit is attributed to autoionization events.

Reactions of Rydberg states of molecular hydrogen
The Journal of Chemical Physics, 1994The Rydberg state reaction H*2+H2→H+3+H+e− was studied by exciting the (X 2∑+g)np,v=0,J Rydberg states with n=30–70 by double resonance excitation via the E,F 1∑+g,v=0,J=1 level and by detecting the product ions or electrons. The results are consistent with the reaction occurring between the ion core of the Rydberg molecule and the ground state ...

Rotational-state-selective field ionization of molecular Rydberg states
Physical Review A, 2007This paper presents state-selective field ionization spectra of highly excited Rydberg states of NO. The competition between electron-nuclear coupling and electron-field coupling is investigated and it is shown that the slew rate of the electric field can be exploited to control the rotational quantum state composition of field-ionized molecules.

Pseudopotential Theory of Atomic and Molecular Rydberg States
The Journal of Chemical Physics, 1966In this paper we present a description of atomic and molecular Rydberg states using an effective Hamiltonian in the one-electron Hartree—Fock approximation. A pseudopotential is introduced to ensure the orthogonality of the Rydberg orbitals to the core. The core is represented by the ground-state wavefunction of the corresponding positive ion. In order

Rydberg State Reactions of Atomic and Molecular Hydrogen
The Journal of Physical Chemistry, 1995Various aspects of the atomic and molecular Rydberg state reactions that result in H[sub 3][sup +] formation by associative ionization and by chemiionization are presented. For associative ionization, the n = 2 Rydberg state was prepared both by direct photodissociation of H[sub 2] and D[sub 2] in the continuum both above the first dissociation limit ...
