【摘要】 本文应用罗辽复提出的构象电子场理论,讨论了视黄醛分子的光致构象跃迁。计算得到的结果表明,视黄醛分子从all-trans构象到1l—cis构象的跃迁几率大于到9—cis构象的跃迁几率,两个几率的比值:10<ω₁₁/ω₉<100。与实验事实和自然界前者优于后者的事实较好地符合。更多还原

【Abstract】 The theoretical concept of Conformation Electron Field suggested by Luo Liao-fu was applied to discuss the light-induced conformation isomerization of a retinene molecule. The result obtained indicates that the isomerization probability of a retinene molecule from all-trans conformation to 11-cis conformation is much larger than that from all-trans conformation to 9-cis conformation. The ratio of the two probabilities is 10<W₁₁/W₉<100. the result is in good accordance with experiment.更多还原
