【Abstract】 Fine structure and hyperfme structure of Mn²⁺in LiNbO₃ crystal have been studied with Electron Spin Resonance（ESR）at room temperature.The energy spacings Δε₁ and Δε₂ due to energy level splitting under the Kramer theorem of energy levels|±1/2〉-|±3/2〉 and |+3/2〉-|±5/2〉of electron spin angular moment nas are Δε₁=-587×10^-4cm^-1and Δε₂=-2633×10^-4cm^-1at zero-field.The anisotropic Lande factors constants g∥and g⊥ areg∥=2.1810,g⊥=2.09368 respectively And the free structure constant D is D=-536×10^-4cm^-1and hyperfme structure constants A∥and A⊥ are A∥=88.36×10^-4cm（-1）A⊥=81.20×10（-4）cm（-1）respectively.Apparently,the interaction of fine structures is much stronger than that of the hyperfme structure.In addition,two sets of forbidden transition between the energy levels |-3/2〉-|1/2〉and|-1/2〉-|5/2〉were found in our experiment.更多还原
