In alicyclic hydrocarbon solvents with aromatic solutes, energy transfer (vide infra) is unimportant and probably all excited solute states are formed on neutralization of solute cations with solute anions, which are formed in the first place by charge migration and scavenging in competition with electron solvent-cation recombination. The yields of naphthalene singlet and triplet excited states at 10 mM concentration solution are comparable and increase in the order cyclopentane, cyclohexane, cyclooctane, and decalin as solvents. Further, the yields of these...

The importance of the size of the solute relative to that of the solvent mentioned above is evident also from experimental determinations of the extent of solid solubility in complex oxides and from theoretical evaluations of the enthalpy of solution of large ranges of solutes in a given solvent (e.g. a mineral). The enthalpy of solution for mono-, di- and trivalent trace elements in pyrope and similar systems shows an approximately parabolic variation with ionic radius [44], For the pure mineral, the calculated solution energies always show a minimum at a radius close to that of the host cation.

If the solutions (energies and wave functions P ) of the Schrodinger equation for the unperturbed system Tf(°) P = F,1,01 4/jl°l are known, and the operator form of the perturbation, Hp, can be specified, the Rayleigh-Schrodinger perturbation theory will provide a description of the perturbed system in terms of the unperturbed system. Thus, for the perturbed system, the SE is...

Erbium and ytterbium ions also display NIR emission in selenium oxychloride (Heller, 1968b). Simple Nd3+ Yb3+ and double Nd3+ -> Yb3+ Er3"1" energy transfers have been investigated. In selenium oxychloride solutions, energy transfer processes depend to a... 

The Cl relaxed density approach [18] should give a more accurate evaluation of the reaction field, but because of its more involved computational character it has been rarely applied in Cl solvation models. The only notably exception is the Cl methods proposed by Wiberg at al. in 1991 [19] within the framework of the Onsager reaction field model. In their approach, the electric dipole moment of the solute determining the solvent reaction field is not given by an expectation value but instead it is computed as a derivative of the solute energy with respect to a uniform electric field. 

Our group has coupled the MST (PCM) method to Metropolis Monte Carlo sampling algorithms (MC-MST [78]). Within this approach cavitation and van der Waals terms are computed as in normal MST, while a semiclassical approach [79, 80] is used to compute the electrostatic component of solvation (see Equation (4.37)). Solute-solute energy terms are computed using a classical force field and Metropolis is then applied to the effective energy shown in Equation (4.38). 

With the help of computer programs and suitable strategy for their use, it is possible to examine a great number of alternative solutions energy-wise and cost-wise and to enhance the evolution to competitive alternatives.

The influence of the ligand field on the electronic states of lanthanides is small and generally of the order of 200 cm-1. Because the ligand field perturbation of J states are minimal, the f-f electronic transitions are sharp. In addition to f-f transitions, both 4f —> 5d and charge transfer transitions are also observed in the spectra of lanthanides [92]. Lanthanide ions exhibit emission in the solid state, and in some cases in aqueous solutions. Energy transfer from the ligand or intermolecularly from an excited state can give rise to the emission from lanthanide ions. 

For the statistical average over the nuclear configurations, generating the distribution over the solute energy gaps (Eq. [18]), one needs to specify the fluctuation statistics of the nuclear reaction field Rp. A Gaussian statistics of the field fluctuations implies using the distribution function...
