Alkenes, Oximes, Imines, Amidines, Azo Compounds

The deformation vibrations of C-H may be either perpendicular to or in the same plane as that containing the carbon-carbon double bond and the other bonds  

The absorption bands due to the out-of-plane vibrations occur mainly at 1000-800 cm (10.00-12.50 gm) and have strong-to-medium intensities.
