Nanosecond transient absorption studies of the lifetimes (5) of several substituted 1 ,n-diphenyl-1 ,n-diyls are reported in polar and non-polar solvents. A para-bromine substituent significantly shortens r. Substitution of OH in the l-position makes the lifetime highly solvent dependent. The substi

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
The magnetic field dependence of the triplet yield of biradicals of the type 2A\*-(CH2).-2D-has been calculated for three different lengths n = 8,9, and 10 of the linking aliphatic chain. The calculations are based on the solution of the stochastic Liouville equation under the assumption of a "throu
