Starting from the formulation of the exchange integral between complex STOS due to Wahl, Cade, and Roothaan, one may obtain a rapidly calculable but approximate form for the two-center exchange integral by successive application of the mean-value the

This study examines the mechanism of hydrotropic solubilization using the riboflavin-nicotinamide system. The most commonly proposed mechanism for hydrotropic solubilization is complexation, and therefore, is investigated. Additionally, since nicotin

Magnetic resonance line positions and intensities are calculated for the simplified spin‐Hamiltonian H=D[Sz2−S(S+1)/3]+g μBH·Swith S=5/2. The resonance line positions and intensities are found by direct diagonalization of the matrix of ℋ and

The spin-Hamiltonian parameters for ZnO: ${\mathrm{V}}^{3+}$ have been refined using electron-paramagnetic-resonance (EPR) line position calculations. The principal sources of error are discussed. The accurate spin-Hamiltonian parameters are used to

Galactose oxidase is a metalloenzyme containing a single copper atom per molecule. The mechanism of action of galactose oxidase is studied in this paper by investigating substrate specificity and activation by peroxidase, and probing the copper site
