摘要：

Efficient but not total triplet-triplet energy transfer is reported between tetralin-1,4-dione and fluorene chromophores held together by a rigid molecular frame at known separation distance and mutual orientation. The exchange mechanism is compared with the alternative resonance-type interaction of admixed singlet character in the lowest triplets. An order-of-magnitude calculation of the exchange-transfer probability gives a result compatible with the observed transfer efficiency. © 1969, American Chemical Society. All rights reserved.
