2. Enhancement of Fluorescence in Thin-Layer Chromatography Induced by the Interaction between n-Alkanes and an Organic Cation

3. Quantitative Applications of Fluorescence and Ultraviolet Scanning Densitometry for Compositional Analysis of Petroleum Products in Thin-Layer Chromatography

4. Procedure details can be found in ref 3a. PM3 semiempirical Hamiltonian at the Hartree−Fock (HF) level was used for a complete geometry optimization of the berberine cation. The ion−molecule complex betweenn-hexane and the berberine cation was optimized at the HF/PM3 level. Finally, geometries of berberine and the berberine−n-hexane complex in the first excited state were optimized at the 3X3CI-HE/PM3 level of theory.
