The solution energies of manganese in LiCl and KCl crystals have been calculated by applying Haven's method to the systems of MnCl_2-Alkali Chloride and by the use of the experimental value of the solution energy of manganese in NaCl, obtaining 0.85eV for LiCl and -2.08eV for KCl. The paramagnetic resonance spectra of manganese in quenched crystals of LiCl and KCl showed the hyperfine structure of divalent manganese ion in the crystalline field with non-cubic symmetry. By assuming the spin Hamiltonian of orthorhombic symmetry for the divalent manganese ion associated with a positive ion vacancy, the values of D and E have been calculated as D = 109±10 gauss and E = 25±10 gauss for LiCl. For KCl the observed spectra and their transformations by thermal treatments will be shown. The coloration of Mn doped crystals was carried out by γ-ray irradiation or by pointed cathode, and the resonance spectra of the colored crystals were observed.
