摘要：
The CrO43- radicals produced by gamma-irradiation in LiNH4SO4 and LiKSO4 crystals exhibit hyperfine splittings due to two magnetically inequivalent protons. This is in contrast to the magnetic equivalence of the proton hyperfine splittings observed for the NH3+ radicals simultaneously produced in these same host lattices. The proton hyperfine splittings of the CrO43- radicals also exhibit much more significant anisotropies than those exhibited by the protons of the NH3+ radicals. These imply a slowing-down of dynamics of the ammonium protons adjacent to the CrO43- radical.
