Reactions of Rydberg states of molecular hydrogen

Journal of Chemical Physics, 1994
The 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 ...

Molecular Rydberg states. VII. Water

Journal of Chemical Physics, 1977
The optical absorption spectra of H2O and D2O are reported at various pressures for 2000?λ?950 Å. The 1670 Å band is vibrationally structured (ν2 bend) and the excited 1B1 state contains a considerable intravalence 4a1 component. The 1280 Å state 3sa1; 1A1 is linear and dominantly Rydberg.

Strong vibronic coupling in molecular Rydberg states

Journal of Chemical Physics, 1984
We 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

Journal of Chemical Physics, 1998
We 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

Molecular Rydberg states. Low-energy Rydberg states of azulene

The Journal of Physical Chemistry, 1983
Electronic 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, 1985
We 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 ...
