Group Frequencies for Fluorocarbons

Group frequency correlations for fluorocarbons are quite limited. It appears that interaction between vibrations occurs more extensively for fluorocarbons than for the corresponding hydrocarbons. Because of this it is difficult to find vibrations for fluorocarbons which remain constant for a series of compounds. Even though the extensive interaction of frequencies of fluorocarbons does not lead to good group frequency correlations, this interaction results in quite distinct spectra for each different type of fluorocarbon structure, so that small structural differences can often be detected by studying the infrared spectra of these compounds. [Pg.283]

The C=N and N=0 stretching vibration can occur in the region from 1690 to 1480 cm , the exact position depending on the structural units attached to the group in question. In allenic-type [Pg.283]

The C=N stretching frequencies appear in the region from 2260 to 2120 cm with variable intensity. [Pg.290]
