We compute the autocorrelation function of the donor-acceptor tunneling matrix element for six Ru-azurin derivatives. Comparison of this decay time to the decay time of the time-dependent Franck-Condon factor {computed by Rossky and coworkers [Lockwood, D. M., Cheng, Y.-K. & Rossky, P. J. (2001) Chem. Phys. Lett. 345, 159-165]} reveals the extent to which non-Condon effects i...

The sample of 1157 radio-identified galaxies from the Las Campanas Redshift Survey (LCRS) (Machalski & Condon 1999) is used to derive the 1.4 GHz luminosity functions of both star-forming (starburst) galaxies with the mean redshift 〈z〉 ≈ 0.07, and AGN-type ones with 〈z〉 ≈ 0.18. These functions are used as a direct measure of their evolution inferred from the evolutionary models of the entire po...

A hysteresis loop is observed for the first time in the de Haas-van Alphen (dHvA) effect of beryllium at low temperatures and quantizing magnetic field applied parallel to the hexagonal axis of the single crystal. The irreversible behavior of the magnetization occurs at the paramagnetic part of the dHvA period in conditions of Condon domain formation arising by strong enough dHvA amplitude. The...

The development of severe retinal vascular disease and retinitis proliferans in sickle cell haemoglobin C disease (SC disease) is well recognized (Welch and Goldberg, I966; Goldberg, 197I; Condon and Serjeant, I972a). In a recent survey in Jamaica, Condon and Serjeant (1972a) noted retinitis proliferans in 23 (33 per cent.) of seventy adults with SC disease. The changes were found in some patie...

Excited-state relaxations in molecules are responsible for a red shift of the absorption peak with respect to the emission peak (Franck-Condon shift). The magnitude of this shift in semiconductor quantum dots is still unknown. Here we report first-principle calculations of excited-state relaxations in small (diameter ≤ 2.2 nm) Si nanocrystals, showing that the Franck-Condon shift is surprisingl...

Franck-Condon effects associated with intervalence excitation of the Creutz-Taube ion (a prototypical delocalized mixed-valency system) have been evaluated via a time-dependent analysis of resonance Raman scattering intensities and the intervalence absorption lineshape. Quantitative studies in the extended near infrared (1320 nm excitation) revealed that at least eight, and possibly nine, vibra...

This feature article discusses some selected aspects in the field of vibrational structure calculations based on vibrational self-consistent field, VSCF, and vibrational configuration interaction, VCI, theory. As the quality of such calculations depends strongly on the accuracy of the underlying multidimensional potential energy surface, PES, some techniques will be discussed to establish high-...
