The Golden Rule. Application for fun and profit in electron transfer, energy transfer, and excited-state decay

Abstract

Time-dependent perturbation theory and application of the Golden Rule have been shown to be quantitatively applicable to electron transfer in the inverted region, energy transfer, and excited-state decay based on spectroscopic measurements on dπ(6) polypyridyl complexes of Ru(II), Os(II), and Re(I).

Diimine ligand structure effects on photophysical properties of tricarbonyl rhenium(I) complexes having arylborane charge transfer units

“…The data demonstrate that the k nr value of ReBbpy or ReBphen is almost half of that of Rebpy or Rephen, respectively, indicating the important role of the DBDE group in determining the nonradiative decay path from the emitting excited state. Generally, the k nr value of the 3 MLCT excited state of a transition metal complex increases with a decrease in the emission energy (ṽ em ), as predicted by the energy gap dependence of k nr : ln k nr = a Âṽ em + constant (a < 0) [49][50][51][52]. However, ReBbpy shows an opposite trend to the prediction by the energy gap law, displaying smaller k nr for the lower-energy emission compared with the k nr andṽ em values of Rebpy.…”

Structure-Based Calculation of Pigment–Protein and Excitonic Pigment–Pigment Coupling in Photosynthetic Light-Harvesting Complexes

“…Then, the exponential term in Eq. (1.28) can be expressed in terms of the emission spectrum of the donor and the absorption spectrum of the acceptor [30][31][32].…”

Molecular-engineered [Ir(Fppy)2(Mepic)] towards efficient blue-emission

“…[39][40][41][42][43] Prior to the spectral fitting analysis, the number of photons at a given wavelength were corrected to the wavenumber scale by using the relationship, 44 …”
