Why are flourescence and phosphorescence spectra measured at a 90 degree angle to the
source?
O To make the overall instrument smaller
O Because the monochromator directs the light at a 90 degree angle
O To ensure that incident (source) photons are not observed
O Because the process of fluorescence and phosphorescence are too intense to be observed directly
O Because the sample cell is darkened on two adjacent sides
