• 中文摘要： 討論溶液中Cr(acac)的EPR 遲緩，可藉著已經考慮 zero-field splitting 作用變動的布朗和跳躍模型而解出Sto-chastic Liouville式，結果顯示與Redfield理論有所偏差，而且EPR的遲緩有複雜衰減振盪的現象，由各種擴散過程計算所得的有效遲緩時間，將于文中討論，有關EPR遲緩效應也一併討論。
• 英文摘要： EPR relaxation of tris-acetylacetonatochromium (III) (Cr(acac)) in solutions has been investigatedby solving stochastic Liouville equation with the consideration of brownian and jump models for the flue-tuation of zero-field splitting interaction. Results show deviations from Redfield theory and complicateddamping oscillations in the EPR relaxations. The inadequate treatment of electron relaxation process byG.C. Levy. and co-workers (1976, J. Chem. Phys., 64,936-941）is pointed out. Effective relaxation timesdue to various diffusion processes are examined. Effects in the EPR relaxations are also discussed.
