Principles of Fluorescence Spectroscopy The quinine in tonic water is excited by the ultraviolet light from the sun. Upon return to the ground state the quinine emits blue light with a wavelength  Applications Using a High Resolution Fluorescence Microscope Namely, some of these fluorescent molecules are quinine, fluorescein However, there are some exceptions to this mirror image rule. Deviation from  Advanced Fluorescence Methodologies its important features such as the Stoke's shift, Kasha's rule and the mirror-image rule. Penetration test using fluorescence imaging. Principles of Fluorescence Spectroscopy - Docenti.unina.it A rigorous test of the mirror-image rule requires that the absorption and emission spectra be presented in appro- priate units.12 The closest symmetry should  Principles of Fluorescence Spectroscopy - Molecules and Code . 7. 1.3.3.
