Identification of ZSM-type and other 5-ring containing zeolites by i.r. spectroscopy

The mid i.r. spectra have been recorded of the pentasil family, of the mordenite group, of ZSM-39 and Melanophlogite, and of the structurally unknown ZSM-34 and ZSM-35. It is concluded that i.r. spectroscopy enables fast differentiation of ZSM-type zeolites.
