  2. Sodium nitroprusside - Wikipedia

    en.wikipedia.org/wiki/Sodium_nitroprusside

    Sodium nitroprusside is often used as a reference compound for the calibration of Mössbauer spectrometers. [54] Sodium nitroprusside crystals are also of interest for optical storage. For this application, sodium nitroprusside can be reversibly promoted to a metastable excited state by blue-green light, and de-excited by heat or red light. [55]
