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 ...

The spectra are EI mass, 1H decoupled 13C NMR, 1H NMR pattern (90 and/or 400 MHz), 1H NMR parameter (300 MHz pattern generated), FT-IR, laser-Raman, and ESR. Web9 Atmospheric pressure strongly affects the absorption spectra of gases (through pressure broadening). This poses a major problem in computing the transfer of IR radiation through the atmosphere with varying pressure, temperature, and amount of gases.

"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. " - Ir spectra list
