Addition of a 20-μL drop of a mixture containing 1 mM Fe²⁺ + 0.5 M glutathione to the surface of 0.5 M S-nitrosoglutathione solution, which is expected to form dinitrosyl iron complexes with glutathione, generated short-lived (0.2 s) concentric ring-shaped structures in the S-nitrosoglutathione solution. The number of the ring-like structures exceeded the number of concentric circles spread across the water surface (mechanical waves) when droplets of water fall into a body of an aqueous solution. It appears likely that the ring-shaped structures observed in the S-nitrosoglutathione solution are associated with an autowave distribution of products generated during the formation of dinitrosyl iron complexes with glutathione.

向0.5 M S-亚硝基谷胱甘肽溶液的表面添加20μL滴的含1 mM Fe ²⁺ + 0.5 M谷胱甘肽的混合物，该混合物预计会与谷胱甘肽形成二亚硝基铁络合物，产生短命（0.2 s）S-亚硝基谷胱甘肽溶液中的同心环形结构。当水滴落入水溶液中时，环状结构的数量超过了分布在水表面（机械波）的同心圆的数量。在S-亚硝基谷胱甘肽溶液中观察到的环形结构似乎与在与谷胱甘肽形成二亚硝酰基铁配合物期间产生的产物的自波分布有关。
