Description:	This report describes the photoacoustic and electron paramagnetic resonance investigations of Brazilian and Cuban zeolites. Photoacoustic optical absorption measurements indicate the presence of iron (Fe) ions with their respective transition bands for both zeolites. Therefore, this work is intended to cover such lack of data and contribute to the zeolite community providing new results.
