COMBINATORIAL METHODS IN ESR SPECTROSCOPY

Combinatorial methods based on the Pólya theory of counting and multinominal expansions are applied to the prediction of the number of hyperfine lines and their intensity patterns arising from the electronic spin and nuclear spin couplings. It is shown that these methods are very useful for predicting the ESR spectral patterns of radicals containing a large number of multinuclear spins. © 1991.
