A Concept for Molecular Addressing by Means of Far-reaching Electromagnetic Interactions in the Visible
摘要： A pronounced concentration dependence of the time constant of fluorescence decay was found, disproving Strickler-Berg’s equation restricting molecular light emission to a local process. Thus, interactions were found significantly extending to more than 100 nm and make such systems promising for interfaces between molecular dots or more complex molecular arrangements and conventional macroscopic electronics.

[Springer Theses] The Electronic Transitions of Molecular Oxygen || Solvent Effects on the O2(a1?g) → O2(b1$$\Sigma_{\text{g}}^{ + }$$) Transition
摘要： In this chapter, we have presented O2(a1Δg) → O2(b1Σ+g) absorption spectra and extinction coefficients for oxygen in 16 solvents. Through the Strickler-Berg equation, these data were converted into the corresponding O2(b1Σ+g) → O2(a1Δg) radiative rate constants to give the first comprehensive set of data on the probability of the O2(b1Σ+g) → O2(a1Δg) transition in solution. With these data in hand, energies and transition probabilities of all three electronic transitions in oxygen have been quantified in a wide range of solvents. We find that our data is consistent with the theoretical framework put forth by Minaev. Nevertheless, our data also suggest that the interaction between oxygen and the solvent takes place through different mechanisms that are simultaneously acting to perturb each of the electronic transitions in oxygen in different ways. In our mind, the system must now be subjected to more systematic and extensive theoretical investigations, in order to quantitatively rationalize these experimental observations.
