摘　　要：Fry等在苯溶液中研究了三乙酰基丙酮合铁[以下用M(AA)_n表示过渡金属乙酰基丙酮配合物]等金属配合物对各种敏化剂激发态的淬灭反应后,认为有两种最可能的淬灭机制,即经由激态复合物的电子能量转移机制和重原子催化系间窜越机制,如下式所示:Using the quenching reaction of α-pinene photoisomerization sensitized by xanthone, the quenching reactivity of transitional metal complexes of acetylacetonate was determined. The rate constants obtained were interpreted based on Dexter theory and an experimental evidence for the electronic energy transfer mechanism of the process is presented.
