✦ Synopsis
Rate constants kq for the quenchmg of the exated state of Ru@rpy)~+ by a serves of vrologen salts havmg drfferent redo\ potentral El,2 hare been determmed in daerated aqueous solutrons at pH = 5 by laser flash photolysls The kq values are found to decrease v. rth mcreasmg -E, ,* and to correlate with the reactron free-energy change AC. Such a correlation IS shown to be consistent wrth the Rehm-Weller model for electron-transfer reactrons
