The possibility of determining the frequency of a purely electronic transition from circular dichroism, circularly polarized luminescence, and magnetically induced optical activity spectra and the spectral dependence of the coefficients of circular dichroism dissymmetry is demonstrated. Examples of such determination from experimentally measured molecular optical rotation spectra in absorption and emission are presented. It was shown that the frequency of a purely electronic transition in the spectral dependences of the dissymmetry coefficients can be indicated by an extremum. As in diffuse linear vibrionic spectra, the frequencies of the purely electronic spectra do not correspond to maxima in the spectra.

从光学活度光谱确定纯电子跃迁的频率

证明了确定由圆二色性,圆偏振发光和磁感应的光学活性光谱确定纯电子跃迁的频率以及圆二色性不对称系数的光谱依赖性的可能性。给出了从吸收和发射中实验测得的分子旋光光谱进行这种测定的例子。结果表明,在不对称系数的频谱依赖性中,纯电子跃迁的频率可以用极值表示。与漫射线性振动离子光谱一样,纯电子光谱的频率不对应于光谱中的最大值。
