WebOn an IR spectrum, certain “peaks” (or rather “valleys”) corresponds to an important resonance frequency of a bond found in your compound. The x-axis is displayed in units of inverse centimeters (cm -1 ), also called “wavenumbers”, which indicates the inverse of the resonance frequency. Generally, higher wavenumbers indicate a ... WebFTIR Spectroscopy, Fourier-transform infrared spectroscopy, is concerned with the vibration of molecules. Each functional group has its own discrete vibrational energy which can be used to identify a molecule through the combination of all of the functional groups.
