摘要
A study of some emission parameters (quantum yield and fluorescence lifetime) for six alkaloid derivatives of beta -carboline is presented. Depending on pH value, various species can exist in solution. In this work we have studied only two of them: cationic and neutral species. The variation of quantum yield and fluorescence lifetime has been analysed for different substituted beta -carboline rings and for some derivatives which do not present the aromatic character on the pyrimidinic nucleus.
