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 ...

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 ...

Lifetime lengthening of molecular Rydberg states in the condensed phase
The Journal of Chemical Physics, 1998We report on fluorescence lifetime lengthenings of molecular Rydberg states in condensed media in the case of the NO molecule trapped in inert gas matrices. In rare gas matrices, the fluorescence of the A 2Σ+ state originates from two types of sites, hereafter called red and main. The red site is considered to be a loose site with more than one vacancy

Formation of molecular Rydberg states in an intense laser field
The European Physical Journal D, 2023 In this paper, we experimentally study the decay constants and the Rydberg states population of molecular ions generated in a strong laser field by using a time-of-flight mass spectrometer.

Molecular Rydberg states. Low-energy Rydberg states of azulene
The Journal of Physical Chemistry, 1983Electronic spectra of azulenes are discussed. The low-energy Rydberg states are emphasized. The 3d-Rydberg states lie at 45,000 to 50,000 cm/sup -1/. They are partially quenched by chemical substituents and totally quenched in condensed media. The 3p-Rydberg states lie at approx. 40,000 cm/sup -1/ in azulene and are largely quenched in all derivatives.

Autoionizing Rydberg States in Triplet Molecular Hydrogen
Physical Review Letters, 1985We report the first observation of the autoinizing triplet $\mathrm{nd}$ series of ${\mathrm{H}}_{2}$ covering the region from $n=10$ to the series limit. The autoionizing states are produced by excitation of ${\mathrm{H}}_{2}$ $c^{3}\ensuremath{\Pi}_{\mathrm{u}}^{\ensuremath{-}}$ molecules in a fast (1 keV) beam with a frequency-doubled pulsed dye ...

Nonexponential autoionization decays in molecular Rydberg states
Physical Review A, 1989Etude des desactivations d'autoionisation des etats de Rydberg nd 1 Λ g de Na 2 en presence d'un faible champ electrique. Dans certaines conditions, on observe des signaux dont la forme differe notablement du comportement usuel. Ces decroissances sont decrites par un modele simple qui rend compte des interactions avec des niveaux discrets et ...

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 ...
