The sentences belоw describe phоtоluminescence phenomenа thаt occur upon the excitаtion of molecular species: (1) Non-radiational process. It involves vibrational levels of the same electronic state. (2) Non-radiational process. It occurs when the high vibrational levels of the lower electronic state overlap with the low vibrational levels of the higher electronic state. (3) Radiational transition between S1 and S0. It occurs from the ground vibrational level of S1 to various vibrational levels of S0. (4) Nonradiative process in which excited states transfer their excess energy to other species, such as solvent or solute molecules. (5) Non-radiative process between electronic states of different multiplicities. It requires a change in electronic spin. (6) Radiational deactivation process between T1 and S0. It occurs from the ground vibrational level of T1 to various vibrational levels of S0. Which one of the following answers gives the correct name to all the process described above? (a) 1 = Fluorescence; 2 = Intersystem crossing; 3 = Vibrational relaxation; 4 = Internal conversion; 5 = Phosphorescence; 6 = External conversion (b) 1= Phosphorescence; 2 = Vibrational relaxation; 3 = Intersystem crossing; 4 = Internal conversion; 5 = Fluorescence; 6 = External conversion (c) 1 = Vibrational relaxation; 2 = Internal conversion; 3 = Fluorescence; 4 = External conversion; 5 = Intersystem crossing; 6 = Phosphorescence (d) 1 = Vibrational relaxation; 2 = Fluorescence; 3 = Internal conversion; 4 = External conversion; 5 = Intersystem crossing; 6 = Phosphorescence (e) 1 = Vibrational relaxation; 2 = Fluorescence; 3 = External conversion; 4 = Internal conversion; 5 = Intersystem crossing; 6 = Phosphorescence
