Prom the temperature dependence of ESR absorption intensity, it is shown that the intermolecular exchange interaction is ferromagnetic in the dilute mixed crystal and antiferromagnetic in the low-temperature phase of the pure crystals. The exchange energy is obtained as 2Jr= 1.5 + 0.7 meV and 2JAF=
