摘要

The CrO^3-₄ radicals produced by λ-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 NH⁺₃ radicals simultaneously produced in these same host lattices. The proton hyperfine splittings of the CrO^3-₄ radicals also exhibit much more significant anisotropies than those exhibited by the protons of the NH⁺₃ radicals. These imply a slowing-down of dynamics of the ammonium protons adjacent to the CrO^3-₄ radical.
