FE-57 MOSSBAUER STUDY OF IRON PHTHALOCYANINE

Phthalocyanines have been noted for their use as chemical sensors. Iro n phthalocyanine (FePc) has been used as a model to elucidate the gas sensing mechanism using transmission Mossbauer spectroscopy to charact erize bulk properties and conversion electron Mossbauer spectroscopy t o study surface interactions. This technique allows an FePc sample to be monitored before, during and after exposure to various gases at amb ient temperatures and pressures, hence mimicking gas sensor operating conditions.
