WebFlash spectroscopy has been used to determine [SH] and [S 2] as functions of time following flash photolysis of H 2 S diluted with CO 2. The rate-determining step in the decay of SH is either (3) or (4), with k3 = 1 × 10 –11 … WebFlash Photolysis Spectrometer is conceived to be a simple, user-friendly device for demonstrating to chemistry students the fundamental principles of Chemical Kinetics. …
WebFlash photolysis of photoactivatable or "caged" probes provides a means of controlling the release—both spatially and temporally—of biologically active products or other reagents of interest. The chemical caging process may also confer membrane permeability on the caged ligand, as is the case for caged cAMP and caged luciferin.
