The absolute configuration (AC) of an axially chiral sulfonate (aCSO), 3,5-dimethyl-2-(naphthalen-1-yl)-6-(naphthalen-1-yl)benzenesulfonate (labeled as aCSO5), was investigated using optical rotatory dispersion (ORD), electronic circular dichroism (ECD), and vibrational circular dichroism (VCD) spectroscopies. All three methods led to the same conclusion and the AC of aCSO5 is reliably determined to be (-)-(aR, aR), or conversely (+)-(aS, aS).
使用旋光色散（ORD）、电子圆二色性（ECD）和振动圆二色性（VCD）光谱法研究了轴向手性磺酸盐（aCSO）3,5-二甲基-2-（萘-1-基）-6-（萘-1-基）苯磺酸盐（标记为aCSO5）的绝对构型（AC）。所有这三种方法都得出了相同的结论，并且可靠地确定aCSO5的AC为（-）-（aR，aR），或者相反地为（+）-（aS，aS）。
