摘要
测定了３种氮氧自由基与环糊精相互作用的ＥＰＲ波谱，计算了波谱参数，结果表明：与环糊精作用后，自由基的超精细分裂常数ａＮ值及旋转相关时间τｃ都有规律变化，由此探讨了氮氧自由基与环糊精作用位点及作用力大小。
Abstract aN and therotational correlation time τc of the radicals change regularly after complexing with cyclodextrins. The magnitude of change in τc is in the order:5DXSA·γCD>5DXSA·αCD>5DXSA·βCD.This can be explained by different in inclusion site and size of the host/guest molecules. The extent o increase in τc values in 4-OHtempo/βCD systems is larger than that in 5DXSA/βCD or 4-palmitoleoylTempl/βCD systems, this is probably due to the best fit of 4-OHTempo to the diameter of inner cavity of βCD molecule.
