A Mössbauer spectroscopy system has been developed which is capable of taking multiple Mössbauer spectra, which are related in time. Its present design is for operation in conjunction with an in-situ electrochemical cell, such that up to 256 Mössbauer spectra can be taken in a dedicated PC. These spectra are uniformly distributed around a cyclic voltammetry looP, which is continually retraced u...
