 Re: Need Help On some questions!!!
Long time since I filled a quartz cell with a liquid and then shone various frequencies of light through it --spectrophotometry. Quenching is only a distant drum beat from far away now, presume that bromide absorbs light emitted as fluorescence and can thus be used to measure it. Am sure would be in basic photometric text book. All tied up with photons and Planck theory of energy levels.
