Excited Electronic States of AuF
The Journal of Physical Chemistry A, 2010We have recorded laser excitation spectra of transitions from the ground X(1)Sigma(+) state of gaseous gold fluoride (AuF) into three excited electronic states in the visible region. We prepared the sample in a dc electric discharge by flowing a dilute mixture of SF(6) in argon through a hollow gold cathode.

Excited States of Porphyrin Macrocycles
The Journal of Physical Chemistry A, 2008S1 --> S(n) spectra of porphyrin, diprotonated porphyrin, and tetraoxaporphyrin dication have been measured in the energy range 2-3 eV above S1 at room temperature in solution by means of transient absorption spectroscopy exciting with femtosecond pulses.

Lifetime of excited atomic states
Physical Review A, 1986In this paper we derive an expression for the lifetime of excited atomic states taking account of contributions due to nonresonant two-photon transitions. Explicit integration of the two-photon emission spectrum is not required. The results are applied to the case of the hydrogen atom.

Excited states in stochastic electrodynamics
Physical Review A, 1988We show that the set of Wigner functions associated with the excited states of the harmonic oscillator constitutes a complete set of functions over the phase space. An arbitrary probability distribution can be expanded in terms of these Wigner functions.

Excited state optical modulator
Applied Optics, 1986It is shown that if two light beams intersect in a medium containing the appropriate molecule, one beam can modulate the other by making use of the differences in the absorption spectra of the ground and excited molecular states. This is possible even with the power of semiconductor lasers.

Chemistry of Excited Electronic States
Science, 1991Atomic and molecular orbitals are among the tools used by chemists to view the world. The validity of this view for reaction systems can be experimentally probed by examination of the chemistry of electronically excited states and, in particular, by comparison of the reactivities of states having different orbital occupations (electron configurations).
