通过对圆二色性（CD）光谱的实验和理论研究，直接确定了苯在胆酸（CA）晶体空腔中的右旋双螺旋（2/1螺旋）排列。实验光谱由苯和CA的手性元素组成，与考虑苯与CA极性基相互作用的理论光谱吻合较好。
The right-handed two-fold helical (2/1 helical) arrangement of benzene included in the cavity of cholic acid (CA) crystal was directly established by experimental and theoretical circular dichroism (CD) spectral studies. Experimental spectra comprised chirality elements of benzene and CA and well agreed with the theoretical spectra which considered interactions between benzene and polar groups of CA.
