of the stilbene system has been investigated, while that of the cinnamarides has previously been reported. The results are consistent with a model in which the reaction takes place in the bulk of crystals composed of random substitutional solid solutions. The model can be refined by considering a slight tendency for like molecules to aggregate in these solutions. There is no evidence for a special
描述了两种肉桂酰胺和两种反式-苯乙烯衍生物体系中的相关系。已经研究了二苯乙烯体系的固态光二聚化,而先前报道了肉桂醛的固态二聚化。结果与模型一致,在该模型中,反应在由无规替代固溶体组成的大部分晶体中发生。可以通过考虑类似分子在这些溶液中聚集的轻微趋势来完善模型。没有证据表明共晶具有特殊的作用。在其中存在中间组成的第三固相的系统中,反应性结果可以通过替代模型来解释。
