The infrared spectra of gaseous (3000-30 $cm-1$) and solid (3000-200 $cm-1$) perfluorovinyldifluoroborane and perfluorovinyldichloroborane have been recorded along with the Raman spectra (3000-30 $cm-1$) of all three physical states. The vibrational data have been interpreted in detail and are consistent with a planar geometry for both compounds. The question of $\Pi$-delocalization through the C-B bond is discussed.
