Abstract
EPR has often been used to define spin states of high spin molecules. This chapter outlines some meaningful considerations for the classification of interacting radicals and the determination of their ground state spin multiplicity. Then a review on different classes of high spin molecules follows, sorted by their spin state, summarizing the application of EPR in that domain.
