    • It is difficult to evaluate the stability of metastable open forms of pyrans in accurate manner, however, comparison of the absorbance at absorption maxima of open-open and closed-open forms permits such a conclusion. In the fatigue-resistance study of the closely-related spiropyrans, it is generally accepted that the open form (merocyanine) is more fatigue-prone than spiropyran itself, see the ref. [25].
