Charge transfer (CT) transitions of optically active carbazoles with chloranil, tetracyanoethylene, and tetracyanoquinodimethane exhibit induced circular dichroism; for five of the six compounds studied the CT complex exhibited two dichroic absorption bands, having positive and negative signs respectively, providing unambiguous evidence of two CT transitions arising from the two highest-energy filled
光学活性咔唑与氯腈,四氰基乙烯和四氰基喹二甲烷的电荷转移(CT)跃迁表现出诱导的圆二色性。对于所研究的六种化合物中的五种,CT配合物表现出两个二向色性吸收带,分别具有正号和负号,为由咔唑衍生物的两个最高能量填充的轨道产生的两个CT跃迁提供了明确的证据。
