A. Draw a well-labeled diagram which shows the singlet state, singlet excited state and the triplet state in a energy level diagram. Show the spin of electrons in each of these states. B. Show transitions in your diagram and label the radiative processes as either phosphorescence or fluorescence C. Discuss which of these are "allowed "transitions and which are "forbidden" transitions
