Ir spectra of nitriles
WebSpectra were recorded of proprionitrile, benzonitrile, and acrylonitrile adsorbed on chromia–silica. The increased frequencies and integrated areas of the nitrile stretching bands, show that nitriles are linked partly to surface silanols through hydrogen bonding and partly to Chromia ‘acidic’ sites through a σ dative bond. The interaction between … WebInfrared Spectroscopy _____ Pre-lab preparation. (1) In Ch 5 and 12 of the text you will find examples of the most common functional groups in organic molecules.
