摘要：

Laser flash photolysis has been used to study the formation of X-2(.-) radical ions (X = Br and Cl) upon photoreduction of ZrCl62- complex in methanal solutions, containing free X-ions. It has been shown that two channels of halogen atom formation are possible. These are the reactions of X-ions with either the primary radical cation CH3OH.+ which results from single electron transfer from a methanol molecule to the excited complex or the intermediate, arising from transformation of primary light-excited ZrCl62- complex.
