Abstract
The goal of this study was to determine the influence of adsorbed molecules on the OH bending vibration, which cannot be directly measured in the fundamental region (750 - 1050 cm-1) because of the strong lattice vibrations of the substrate. The only way is to measure the combination vibrations in the near infrared. The Diffuse Reflectance Infrared Fourier Transform (DRIFT) technique was used to study the whole spectral range from the fundamental vibrations of OH groups to the overtones in the near infrared (3000 - 7500 cm-1) on the same sample. Several OH groups with different acidity on silica and crystalline alumosilica (zeolites) have been investigated.
