## AhStNCt The recombination kinetics of protonated and perdeuteriated chain-linked ( ( CH2), linker, n = 3, 6, and 10) triplet ketylphenoxyl radical pairs (RP ) have been examined by using the laser flash technique under an external magnetic field. The high values of magnetic isotope effect (MIE)
Lanthanide g-diketonates and copper acetylacetonate in benzene quench the methylene-chain-linked triplet biradicals in the presence of magnetic fields. At 0.56 T, the quenching rate constant k, is in the order of IO8 M-' SK' for the former complexes and 4.7 x lo9 M-' s-' for the latter. Dipole-dipol
