Describe two major reasons why fluorescence spectrophotometry is a very sensitive analytical technique? (hint, one of the reasons involves the equation I = KP0C) If you wish to analyze a molecule using fluorescence spectrophotometry but that molecule does not fluoresce, what can you do? What characteristics of a molecule make it likely to fluoresce?
