首次用X射线晶体学方法直接证实了光致变色吡唑啉酮类化合物的结构变化。在光致变色过程中，伴随着质子转移，发生烯醇和酮形式异构体之间的互变异构转化。
Structural changes of photochromic pyrazolones were first verified by an X-ray crystallographic method directly. A tautomeric transformation between enol and keto form isomers occurs, accompanied by proton transfer during the photochromic processes.
