Abstracts

EN

The rate constants, k_{SE}, of ortho- into para-positronium spin conversion reactions promoted by paramagnetic 3d complexes may be correlated with their electronic constitution as it is described by the spin-orbit coupling and interelectronic repulsion parameters. The correlation is explained in terms of unpaired metal-electron delocalization towards the complex boundaries.
