✦ Synopsis

The formation of complexes between triplet excited and ground state molecules (triplet exciplexes) has attracted much interest, particularly in connection with the quenching of triplet ketones by amines', olefins', aromatic and aliphatic hydrocarbons'. A considerable body of evidence has given direct support for the intermediacy of a charge-transfer (CT) complex, (A-B+), in many

## Abstract Paramagnetic nickel(II) complexes which are used as commercial photostabilizers of polyolefins are shown in laser photolysis studies to quench the triplet state of benzophenone in dilute benzene solution. The efficiency of quenching observed is less than that of diamagnetic square‐plana
