This paper is the first systematic review of experimental research on diamagnetic (aka Condon) domains that form in nonmagnetic metals at low temperatures due to the development of Landau levels. A variety of methods were used to study the domains.

Accounting for Evil and Cruelty: Is to Explain to Condone?
Personality and Social Psychology Review, 1999Analysts of evil and violence express the concern that to explain harmdoing may result in a condoning attitude toward perpetrators. An examination of research relevant to this hypothesis suggests that there are a variety of cognitive and affective processes that may produce a relatively condoning attitude toward perpetrators as a result of explaining ...

Nonclassical Franck-Condon processes
Chemical Physics Letters, 1993Abstract Franck-Condon factors govern many important molecular processes, including electronic spectroscopy and radiationless transitions. A better understanding of the propensities for exciting various kinds of motion in nonclassical, nonvertical transitions is necessary to attach the right significance to certain experiments.

Oscillating Franck-Condon factors
Chemical Physics Letters, 1993Abstract The strength of the coupling between two normal vibrations of the same symmetry depends in the Born-Oppenheimer approximation upon the electronic state of the molecule. The consequences of a time-dependent relaxation of this coupling are investigated. Such a relaxation can be brought about either by an electronic excitation or by a forced re-

A Study of the Franck-Condon Principle
The Journal of Chemical Physics, 1936The validity of the Franck-Condon principle has been investigated in connection with its application to the calculation of spectral intensities in the continuous radiation due to the transitions between the 1sσ2sσ 3Σg and the 1sσ2pσ 3Σu states of H2.

The Franck-Condon Principle is a thread running through all of molecular spectroscopy and much of atomic and molecular physics. Many dynamical problems require the evaluation of nuclear motion wavefunctions and overlap integrals; and product distributions are often governed by the squares of such integrals, i.e. by Franck-Condon factors.

Israel Journal of Chemistry, 1993
AbstractA theoretical basis for the solvation dynamics study of complex molecules in solutions by resonance four‐photon spectroscopy has been developed. A non‐Markovian theory of four‐photon spectroscopy of electronic transitions in complex molecules has been generalized for the “non‐Condon” tensor case.

An Algebraic Treatment of Franck-Condon-Transitions
Physics of Condensed Matter, 1974A purely algebraic evaluation of Franck-Condon-Integrals, of transition rates for energy conserving Franck-Condon-transitions and of the related thermal averaged quantities is performed.

‘Condon Parabolæ’ in Molecular Spectra [PDF]
Nature, 1962 IN his original paper on the quantitative explanation of the Franck–Condon principle, Condon1 predicted the expected locus of strong bands on the v′, v″ plane by classical mechanics and the correspondence principle. For simple harmonic oscillator potentials he predicted a quadratic relationship between v′ and v″ which can be compared with the position ...

The Franck–Condon principle and the sudden approximation
Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2009The corrections to conventional Franck-Condon factors required by the assumption that an electronic transition takes place in a non-zero time t(0) are investigated using a theory based on the sudden approximation. An explicit expression using a harmonic oscillator model is given for the vibrational progression k'
