The synthesis of several so far unknown mono- and oligo-galvinols and galvinoxyls is described. The ESR hyperfine splitting measurements in liquid solution indicate that the spin exchange frequency is greater than the hyperfine splitting in the galvinoxyl biradicals (J≫a). The electronic absorption spectra of the galvinols and galvinoxyls are discussed taking into account the different prototropic and redox equilibria, respectively. Using magnetic susceptibility measurements the singlet-triplet and doublet-quartet splitting is studied.
