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 ... WebFor example, the most characteristic absorption band in the spectrum of 2-hexanone (Figure 6.3a) is that from the stretching vibration of carbonyl double bond C=O at 1716 cm-1. It is a very strong band comparing to the others on the spectrum. A strong absorbance band in the 1650–1750 cm-1 region indicates that a carbonyl group (C=O) is present. hovda orthodontics
