本文应用唐敖庆等人的配位场理论方法,分析SO(3)-D_n群的变换,引进了D_n群不可约表示特征M的概念,统一给出了[-1]~Γ、[-1]~γ因子,SC(3)-D_n群S_(mГγ)~i系数,D_n群V系数,D_n群不可约表示[Г~2]和(Г~2),交换因子(-1)~Г、θ(Г_MГ_MГ_M’)等.并得到求SO(3)-D_n群V系数的公式,直接沟通SO(3)-D_n群链.并应用SLJГγ稀土偶合方案对EuP_5O_(14)基态谱项~7F能谱作了分析.
In this paper, by applying the coordination field theory method of Tang Ao-qing et al., We analyze the transformation of SO (3) -D_n group and introduce the concept of irreducible representation of feature M of D_n group. We give the unified definitions of [-1] ~ Γ, [-1] ~ γ factor, S m mγγ coefficient of SC (3) -D_n group, V coefficient of D_n group, irreducible D_n group represent [Г ~ 2] and (Г ~ 2), exchange factor (-1) ~ Г, θ (Г_MГ_MГ_M ’), etc. The SO (3) -D_n group chain is obtained through the formula for obtaining the V coefficient of SO (3) -D_n group, and the ground state spectrum of EuP_5O_ (14) ~ 7F can be obtained by the SLJ- Spectrum analysis.
