TLDR
In this article, a mechanism consistent with the above observations has been proposed and verified for the selective oxidation of thioethers to sulphoxides and of PPh3 to pPh3O using NMO in DMF as solvent in the presence of Ru(III) chloride as catalyst.Abstract:
The selective oxidation of thioethers to sulphoxides and of PPh3 to PPh3O can be effected by NMO in DMF as solvent in the presence of Ru(III) chloride as catalyst. Kinetic investigations indicate that the orders with respect to the catalyst and oxidant are one each. The order with respect to the substrate is variable being fractional order at low concentrations and zero at high concentrations. Spectrophotometric studies reveal the formation of a 1:1 complex between the substrate and the catalyst. A mechanism consistent with the above observations has been proposed and verified.read more

TL;DR: Chandross, Longworth, and Viscoz as discussed by the authors showed that the emission spectrum comprises two or more components, the spectral distribution of the component shortest in wavelength is similar to that of anthracene fluorescence, but the others are broad, structureless, and located toward the red with respect to the first component.
