在硫酸小檗碱存在下的烷烃提供荧光信号的增强，这取决于烷烃的浓度和结构，当用单色UV光照射系统时。计算分析表明，离子诱导的偶极子之间的烷烃和硫酸小檗碱是负责这一现象。这种相互作用可以适当地模拟实验获得的荧光响应。所提出的解释允许设计其他相互作用的系统，这已经被实验证实。
Alkanes in the presence of berberine sulfate provide an enhancement of fluorescent signal, which depends on alkane concentration and structure, when the system is irradiated with monochromatic UV light. Computational analysis suggests that an ion-induced dipole between alkanes and berberine sulfate is responsible for this phenomenon. This interaction can properly model the experimentally obtained fluorescent response. The proposed explanation allows other interacting systems to be designed, which have been experimentally confirmed.
