Heller, A

A theory is proposed to explain the relationship between the structure and the scintillation efficiency of organic liquid scintillators. The requirements for good scintillation properties in given solvent-solute systems include the existence of pairs of energy levels in the solute which are identical with those involved in the excitation of the solvent, and a non-rigid structure in the solute capable of undergoing conformational changes in the excited state. It was found that the behavior of liquid scintillators satisfied these requirements. A hitherto unkown scintillator, 9-vinylanthracene, for which good scintillation properties were predicted, was indeed found to be a high-grade primary or secondary scintillator, capable of replacing the expensive POPOP.
