They attributed that the presence of extensive inner filter effects and resonance energy transfer in petroleum fuels are the major causes of the distinctive characteristics of these spectra in adulterated samples. Together both the authors later on developed total synchronous fluorescence scan spectra to understand petroleum products and showed that total synchronous fluorescence scan profile is different from excitation emission matrix fluorescence. Digambara along with his collaborator Dr. Rohit Kumar Rana at Indian Institute of Chemical Technology designed a new type of microcapsule-embedded fluorescent molecule
