The IR spectrum of a solid can be taken by dissolving it to create a solution. An appropriate solvent is __________because its IR stretches are ______ - The IR spectrum of a solid can be taken by dissolving it to create a solution. An appropriate solvent is [tetrachloromethane] because its IR stretches are [only in the fingerprint region]. Predict the frequency range (in cm-1) of each described structural feature. O-H stretch in a carboxylic acid C=O stretch in an aldehyde C-N stretch in an amine -C=C- stretch in an aromatic ring - O-H stretch in a carboxylic acid → , C=O stretch in an aldehyde → , C-N stretch in an amine → , -C=C- stretch in an aromatic ring → What types of IR sample preparation are appropriate to use between two salt plates? - A pure, undiluted liquid sample, A solid sample dissolved in an organic solvent, like dichloromethane, A solid sample ground into a powder and mixed with mineral oil If an unknown compound has a moderately intense, wide peak in the cm-1 region, what functional group is likely present? - alcohol Radiation in the infrared (IR) range is______ in energy than visible or ultraviolet light. When a molecule absorbs IR radiation, ______ within the molecule and each
