C-h stretching vibration peak
Web10.2 If chloroform (trichloromethane) exhibits an infrared peak at 3018 cm-' due to the C-H stretching vibration, calculate the wavenumber of the absorption band corresponding to the C-D stretching vibration in deuterochloroform (experimental value 2253 cm-'). 10.3 A ketone possesses an absorption band with a peak centred around 1710 cm -. WebTherefore, the peak at the wavelength of 3430 cm −1 only indicates a O–H stretching vibration. The peaks at 1618–1629 cm −1 could represent the ketonic C=O group. For RHB, the peak at 1564 cm −1, attributed to the C–O+ stretching vibrations of the oxonium groups, contributes to the protonation on the surface of the material .
