摘要：

The photoreduction of benzophenone with thiophenol was studied by a laser flash photolysis under the magnetic fields of 0-10 T. The escape yields of the benzophenone ketyl and phenylthiyl radicals decreased with increasing magnetic field strength. The observed magnetic field effect can be interpreted by the Ag mechanism in the case of a triplet radical pair.
