EPR DETECTION OF RADICAL COMPLEXES H-CENTER-DOT-CENTER-DOT-CENTER-DOT-HF FORMED IN THE REACTION OF THERMAL F ATOMS WITH H-2-MOLECULES IN ANAR MATRIX

Reaction of thermal F atoms with H-2 in an Ar matrix is shown to yield uniquely H ... HF complexes, whereas the same reaction of translation ally-excited F atoms gives isolated H atoms.
