Light Induced Metastable State of Silver Nitroprusside Probed by Raman Spectroscopy

摘要

Low temperature Raman spectroscopic measurements on silver nitroprusside (AgNP), Ag_2[Fe(CN)_5NO] powders display reversible features of a partially converted metastable state. The results are compared with similarly observed metastable state in case of sodium nitroprusside (NaNP) and the differences have been discussed in terms of possible resistance to metastable state formation offered by silver atoms on the basis of hard soft acid base (HSAB) theory.
