The odd–even behavior of n‐alkanes shows that polyene molecules can be minority trapped in the crystalline phase of these saturated compounds, forcing to the fraction of trapped polyenes to adopt an all‐trans structure very close to coplanar. This evidence helps us explain the photophysical behavior of these important compounds based on conformational changes of their molecular structure.

温度从293降至77 K时多烯溶解在正构烷烃中的光物理性质

正构烷烃的奇偶行为表明，在这些饱和化合物的结晶相中，多烯分子可以被少数捕获，从而迫使捕获的多烯中的一部分采取非常接近共面的全反式结构。该证据有助于我们根据分子结构的构象变化来解释这些重要化合物的光物理行为。
