✦ Synopsis

Conventional photoexcitation spectroscopy is supplemented with phosphorescence microwave double resonance techniques to produce a method for studying the mechanisms of energy transfer processes in molecuh crystals. The results clearly show that in doped mixed crystals of limited guest-in-host sofubility, triplet-triplet energy transfer is more important than singlet-singlet energy transfer in pumping the lowest triplet state of the guest molecuk when the singlet state of the h&t is excited. -
