观察了β-环糊精(β-CDX)与邻−、间−和对二取代苯形成的络合物的诱导圆二色谱。对观测到的转动强度与用柯克伍德-提诺科公式计算的转动强度进行了比较，给出了β-CDX空腔中客体分子的可能取向。这些结果表明客体分子的取向被限制在β-CDX环面的轴线上。
The induced circular dichroism (ICD) spectra of β-cyclodextrin (β-CDx) complexes with o−, m−, and p-disubstituted benzenes were observed. The comparison of the observed rotational strengths with the ones calculated by using the Kirkwood-Tinoco expression is examined; the possible orientations of the guest molecules which are included in the cavity of β-CDx are presented. These results suggest that the orientation of the guest molecule is confined about the axis of the β-CDx torus.
