TL;DR: In this paper, the temporal correlations of thermodynamic concentration fluctuations have been measured in a chemically reactive system at equilibrium by observing fluctuations of the fluorescence of a reaction product, and the experiment yields the chemical rate constants and diffusion coefficients and shows the coupling among them.

TL;DR: In this article, a method for determining chemical kinetic constants and diffusion coefficients by measuring the rates of decay of spontaneous concentration fluctuations was proposed, which is based on the principle that the rate of spontaneous microscopic fluctuations are determined by the same phenomenological rate coefficients as those of macroscopic departures from equilibrium which result from external perturbations.

TL;DR: This paper describes the first experimental application of fluorescence correlation spectroscopy, a new method for determining chemical kinetic constants and diffusion coefficients by observing the time behaviour of the tiny concentration fluctuations which occur spontaneously in the reaction system even when it is in equilibrium.

TL;DR: More precise values have been obtained for two previously proposed absolute quantum yield standards for the rhodamine 6G cation and the fluorescein dianion dyes in nine solvents.

TL;DR: Fluorescence spectra of polymetalloles or metallole-silane copolymers obtained in either toluene solutions or thin polymer films displayed no shift in the maximum of the emission wavelength, which suggests that the polymetaloles or meetalloles-silanes exhibit neither pi-stacking of polymer chains nor excimer formation.
