TLDR
In this paper, the decay process of qua- si-isolated molecules is studied in the case of strong coupling, where the effects of regularities in the level spacing and the distribution of the oscillator strength in the manifold determine the long time behavior.About:

Eigenstate‐resolved unimolecular reaction dynamics: Ergodic character of S0 formaldehyde at the dissociation threshold
TL;DR: In this paper, the Stark level-crossing spectra of S0 D2CO were analyzed for evidence of energy level correlations and quantum ergodicity, and the analysis for short and long range level correlations gave an apparent energy level spacing distribution which lies between the Poisson and GOE limits.
Journal ArticleDOI
Subpicosecond fluorescence dynamics of dye molecules
TL;DR: In this article, the authors analyzed data obtained recently by the up-conversion technique together with new results: access to vibrational coherence effects and to vibration redistribution, thermalization, and cooling for fluorescent dyes.

The electronic relaxation of biacetyl in the vapor phase
R Vanderwere,Jan Kommandeur +1 more
TL;DR: In this article, the emissions of biacetyl after pulsed dye-laser excitation were studied at pressures down to 0.05 mtorr and the authors determined the low-pressure emission characteristics and the pressure effects as a function of excitation energy.
Journal ArticleDOI
Average singlet–triplet coupling properties of biacetyl and methylglyoxal using quantum beat spectroscopy
TL;DR: In this paper, the authors have observed quantum beats in the reversible intersystem crossing of simple α-dicarbonyls and analyzed them to obtain information concerning the density of interacting states and the average intramolecular coupling energy.

The energy gap law for radiationless transitions in large molecules
Robert Englman,Joshua Jortner +1 more
TL;DR: In this article, a unified treatment of non-radiative decay processes in large molecules which involve either electronic relaxation between two electronic states or unimolecular rearrangeme(s) is presented.

Intramolecular Radiationless Transitions
Mordechai Bixon,Joshua Jortner +1 more
TL;DR: In this paper, the authors considered a theory for intramolecular radiationless transitions in an isolated molecule and derived the validity criteria for the occurrence of an unimolecular radii-less transition and for exponential decay.

Multiphonon Processes in the Nonradiative Decay of Large Molecules
Karl F. Freed,Joshua Jortner +1 more
TL;DR: In this paper, the role of the Franck-Condon principle in determination of nonradiative decay rates of polyatomic molecules has been investigated in terms of statistical analysis.

Long Radiative Lifetimes of Small Molecules
Mordechai Bixon,Joshua Jortner +1 more
TL;DR: In this paper, the authors applied a theory of electronic relaxation in polyatomic molecules for the study of the anomalously long radiative lifetimes of NO2, CS2, and SO2.

Radiationless Transitions and Molecular Quantum Beats
Joshua Jortner,R. Stephen Berry +1 more
TL;DR: In this article, the authors have classified molecules exhibiting vibronic mixing into two extreme cases, which they call the resonant case and the statistical case, characterized by low and high densities of molecular eigenstates, respectively.
