    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.

  2. The following table lists infrared spectroscopy absorptions by frequency regions.

  3. Peak Positions. The equation(4) gives the frequency of light that a molecule will absorb, and gives the frequency of vibration of the normal mode excited by that light. (4) Only two variables in equation(4) are a chemical bond's force constant and reduced mass.

  4. 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.

  5. 11 lut 2023 · Table of Common IR Absorptions. Note: strong, medium, weak refers to the length of the peak (in the y axis direction). Note: spectra taken by ATR method (used at CSB/SJU) have weaker peaks between 4000-2500 cm -1 compared to reference spectra taken by transmittance methods (typical on SDBS and other sites).

  6. The carbonyl stretching absorption is one of the strongest IR absorptions, and is very useful in structure determination as one can determine both the number of carbonyl groups (assuming peaks do not overlap) but also an estimation of which types.
