Multiphoton Spectra and States of Halogens
J. C. D. Brand,A. R. Hoy +1 more
TL;DR: In this paper, the Franck-Condon effect was used to prevent the simultaneous excitation of two o r three photons using the conveniently placed, low-lying excited sQtes in the visible region for the initial step, in effect broadening the perspective from the ground state to include that from lower ex...

Ar–I2 interactions: The models based on the diatomics‐in‐molecule approach
A. A. Buchachenko,N. F. Stepanov +1 more
TL;DR: In this article, a semiempirical model is developed for studying the electronic structure of the rare gas atom-halogen molecule systems, formulated in the frame of diatomics-in-molecule (DIM) approach and taking explicitly into account strong spin-orbit coupling pertinent to heavy halogen molecules.

Spectroscopy and relaxation dynamics of I2Arn clusters. Geminate recombination and cluster fragmentation
TL;DR: In this article, I2Arn clusters yield visible and near-UV emissions when excited to the states which correlate with the first ion-pair manifold of I2, and they also indicate that dissociation, recombination, and fragmentation processes may be used as a general method for generating metastable species in supersonic expansions.

Role of Kinetic Energy in the Franck–Condon Principle
Abstract: During an electronic transition in a molecule the nuclear positions and momenta (hence kinetic energies) both tend to remain fixed according to the Franck principle According to the quantum mechanical Franck–Condon principle, the most probable changes in vibrational quantum numbers or nuclear energy conform to the Franck principle As usually implemented, it is assumed that the most probable nuclear‐energy transitions are approximately at frequencies corresponding to the R values (R = internuclear distance) of classical turning points of the nuclear motion, where the classical kinetic energy is zero It is shown here for some model diatomic cases that, in transitions to or from a bound state with enough vibrational energy, an equally strong maximum of transition probability as a function of frequency can occur classically corresponding to R values where the nuclei in the initial state have maximum kinetic energy Quantum mechanically, this means for example that in such cases, transitions to states of th
