Abstract
A method has been devised to prepare CF2 = CD2 and CF2 = CHD. The infrared spectra of the gaseous compounds and the Raman spectra of the liquids have been determined. The observed frequencies have been assigned to the fundamental modes of vibration and to overtones and combinations. The torsional frequency has been estimated as ca 720 and ca 520 cm—1 in CF2 = CH2 and CF2 = CD2, respectively. The overtone of the torsional frequency interacts with the CH2 or the CD2 deformation fundamental and this is the cause of the anomalous results with the product rule.Keywords
