Multiple Mössbauer Spectra Data Acquisition with an In-situ Cyclic Voltammetry System
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 until sufficient statistics are accumulated. This system was used to acquire four spectra of a Prussian-blue-modified graphite paste electrode, while the electrode was involved in an electrochemical process. The spectra show differences due to the reduction and oxidation of the iron in Prussian blue.
