Assuming that the dipole moment of a molecule is zero in its electronic ground state (S0) and is µ in its first excited state (S1). If the molecule is dissolved in a polar solvent, describe the time evolution of the fluorescence spectrum following an ultrashort laser pulse excitation which excites the molecule to higher vibrational states of S1 in following cases: A. Intramolecular vibrational relaxation (IVR) is faster than solvation process; B. IVR is slower than solvation process; C. IVR and solvation occur at similar time scale.
