The rotatory dispersion and circular dichroism spectra of several ketones conjugated with an aromatic ring (derived from diterpenoids and steroids) have been studied. These compounds show Cotton effect curves with peaks near 350mμ. Extremely weak UV absorption maxima in the 320- 350 mμ region can be detected for these ketones in iso-octane solution. This would indicate that the perturbing light wave
研究了几种与芳香环共轭的酮的旋转分散和圆二色性光谱(衍生自二萜和类固醇)。这些化合物显示出棉花效应曲线,其峰值接近350mμ。可以在异辛烷溶液中检测到这些酮在320-350mμ区域内极弱的紫外线吸收最大值。这将表明,扰动的光波在这样的共轭酮中诱导出非常小的电偶极矩,但引起了很大的磁偶极矩。
