An abnormal phenomenon in the raman spectrum of yb2o3 is found . it is supposed that the special raman spectrum may be the mixed or coupled spectra of the electronic raman spectrum of yb3 + and the vibrational raman spectra of yb2o3 . the special raman effect of yb2o3 may be related to some key questions about the theory of the electronic raman spectra 作者认为, yb _ 2o _ 3特殊的拉曼光谱可能反映的是yb ~ ( 3 + )的电子拉曼光谱与yb _ 2o _ 3的振动拉曼光谱的混合谱或耦合谱, yb _ 2o _ 3特殊的拉曼光谱效应,可能涉及电子拉曼光谱理论的关键问题。
