I n studies involving an energy transfer process it is important to have definite knowledge of the excited state of the solute which is responsible for the emitted fluorescence that is measured. When solutions with low solute concentration are irradiated with ionizing particles, the initial excitations are produced in the solvent molecules (excited molecules or ions). The excited solvent molecules and ions can transfer energy to the solute producing excited solute molecules. The measured scintillations are the result of the return of the solute molecules to the ground state.
