Development of organic scintillators
Transitions made by the free valence electrons of the molecules are responsible for the production of scintillation light in organic crystals. These electrons are associated with the whole molecule rather than any particular atom and occupy the so-called -molecular orbitals. The ground state S0 is a singlet state above which are the excited singlet states (S , S , ...), the lowest triplet state (T0), and its excited levels (T , T , ...).
