| Abstract: | IR spectra are reported for, in which X represents various polar substituents and Y a bridge with multiple bonds. There is a linear relation between the frequency of the vE
C-F(H) degenerate vibration and Taft's induction constant  * for the radical attached to the CF3 group. Frequency vE
C-F is also correlated with the n, which shows that the conjugated system can transmit the electron effect of X to the CF3 group. Compounds are compared as regards this transmission, and some features of the frequencies of the multiple bonds are elucidated.See6, 7] for brief details of the spectra of some of the compounds. |
