A simple anal. expression for the Evans window in the IR absorption spectrum of hydrogen-bonded basic mols. in protonic zeolites is presented. The expression shows that the essential parameters are the position of the shifted \"uncoupled\" OH stretching frequency, its width, the position of the in-plane bending overtone and the coupling of this mode with the OH stretching mode. Anal. of the Fermi resonances in the OH stretching band profile provides a method to det. whether adsorbed mols. are hydrogen bonded or protonated. [on SciFinder (R)]
