Phosphorescence Microwave Photoexcitation Spectroscopy: A New Technique for the Study of Energy Transfer in Molecular Crystals.
Abstract
Conventional photoexcitation spectroscopy is supplemented with phosphorescence microwave double resonance techniques to produce a method for studying the mechanisms of energy transfer processes in molecular crystals. The results clearly show that in doped mixed crystals of limited guest-in-host solubility, triplet-triplet energy transfer is more important than singlet-singlet energy transfer in pumping the lowest triplet state of the guest molecule when the singlet state of the host is excited.
