Problems in the IR measuring the acidity of zeolite bridging hydroxyls by low-temperature CO adsorption.
Two infrared OH stretching bands are produced after interaction of CO with H-ZSM-5 bridging hydroxyls. These two bands are not due to heterogeneity of the acid sites but arise from Fermi-resonance.
