Abstract
[GRAPHICS] Alkanes in the presence of berberine sulfate provide an enhancement of fluo rescent signal, which depends on alkane concentration and structure, when t he 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 all ows other interacting systems to be designed, which have been experimentall y confirmed.
