- 6.3: IR Spectrum and Characteristic Absorption Bands
An infrared spectroscopy correlation table (or table of infrared absorption frequencies) is a list of absorption peaks and frequencies, typically reported in wavenumber, for common types of molecular bonds and functional groups.
IR Chart. Spectroscopy Tutorial: Reference. Table of Characteristic IR Absorptions. You can download this chart as a printable acrobat pdf file. m=medium, w=weak, s=strong, n=narrow, b=broad, sh=sharp.
Table of IR Absorptions. All figures are for the typical case only -- signal positions and intensities may vary depending on the particular bond environment.
16 Δεκ 2021 · The absorption bands in IR spectra have different intensity, that can usually be referred to as strong (s), medium (m), weak (w), broad and sharp. The intensity of a absorption band depends on the polarity of the bond, the bond with higher polarity will show more intense absorption band.
The following table provides a collection of such data for the most common functional groups. Following the color scheme of the chart, stretching absorptions are listed in the blue-shaded section and bending absorptions in the green shaded part.
The IR Spectrum Table is a chart for use during infrared spectroscopy. The table lists IR spectroscopy frequency ranges, appearance of the vibration and absorptions for functional groups. There are two tables grouped by frequency range and compound class. IR Spectrum Table by Frequency Range.
