It has been revealed that the crystalline state photo isomerization reaction of the orgarno-dirhodium dithionite complex could be observed by X-ray crystal structure analyses when the crystal specimens were irradiated by the light not on the absorption maxima but on their skirts. Moreover, it was clarified that the first-order phase transition happened at the early stage of the light irradiation, and the structural change according to this phase transition is the same as that occurred at the temperature phase transition, and also the photo induced phase transition seems to be originated in the entropy effect related to the isomer generated with the photo isomerization reaction.

用X-射线晶体结构分析表明，当光照射晶体样品时，可以观察到连二亚硫酸二铑配合物的结晶态光异构化反应。此外，它被澄清，一级相变发生在光照射的早期阶段，根据该相变的结构变化是相同的，发生在温度相变，而且光诱导相变似乎起源于与光异构化反应产生的异构体有关的熵效应。
