Group Frequency Regions

Table 22.1 Stretching Frequencies found in Group Frequency Region... Table 22.1 Stretching Frequencies found in Group Frequency Region...
The group frequency region falls approximately between 4000 to 1400 cm-1, and the absorption bands in it may be assigned to vibration of pairs of two (or sometimes three) atoms. The frequency is characteristic of the masses of the atoms involved and the nature of their bond, ignoring the rest of the molecule. Therefore, IR spectra are useful for determining the presence of functional groups in organic compounds alcohols (—OH), ketones (=CO), amines... [Pg.18]

An unknown compound shows vibrational absorbances occurring at 3287, 2215, and 729 cm. Keeping in mind that these are not all of the vibrational frequencies of the molecule, use the concepts of group frequency regions and correlation tables to determine whether or not such absorptions are likely for the following molecules. [Pg.516]
